+It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).</p><p>Features:</p>
+<ul>
+<li>Panel with taskbar, system tray, clock and launcher icons;</li>
+<li>Easy to customize: color/transparency on fonts, icons, borders and backgrounds;</li>
+<li>Pager like capability: move tasks between workspaces (virtual desktops), switch between workspaces;</li>
+<li>Multi-monitor capability: create one panel per monitor, showing only the tasks from the current monitor;</li>
+<li>Customizable mouse events.</li>
+</ul>
+<p>Goals:</p>
+<ul>
+<li>Be unintrusive and light (in terms of memory, CPU and aesthetic);</li>

+<h3 id="introduction">Introduction<a name="introduction" href="#introduction" class="md2man-permalink" title="permalink"></a></h3><p>These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface <code>tint2conf</code>.</p><p>The first time you run tint2, it will create the config file in <code>$HOME/.config/tint2/tint2rc</code> (This applies if you have done a clean install. Running tint2 in the source directory without doing &#39;make install&#39; will not create the config file.)</p><p>You can also specify another file on the command line with the -c option, e.g.: <code>tint2 -c $HOME/tint2.conf</code>. This can be used to run multiple instances of tint2 that use different settings.</p><p>If you change the config file while tint2 is running, the command <code>killall -SIGUSR1 tint2</code> will force tint2 to reload it.</p><p>All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.</p><h3 id="backgrounds-and-borders">Backgrounds and borders<a name="backgrounds-and-borders" href="#backgrounds-and-borders" class="md2man-permalink" title="permalink"></a></h3><p>The tint2 config file starts with the options defining background elements with borders:</p>
+<ul>
+<li><p><code>rounded = number_of_pixels</code> : the corner radius</p></li>
+<li><p><code>border_width = integer</code> : the border width in pixels</p></li>
+<li><p><code>border_sides = LRTB</code> : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used. <em>(since 0.12.12)</em></p></li>
+<li><p><code>background_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).</li>
+</ul></li>
+<li><p><code>border_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+<li><p><code>background_color_hover = color opacity</code> (default: same as <code>background_color</code>) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)</li>
+</ul></li>

+</ul></li>
+<li><p><code>background_color_pressed = color opacity</code> (default: same as <code>background_color_hover</code>) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)</li>

+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+</ul>
+<p>You can define as many backgrounds as you want. For example, the following config defines two backgrounds:</p><pre class="highlight plaintext"><code>rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+</code></pre>
+<p>tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:</p><pre class="highlight plaintext"><code>panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+</code></pre>
+<p>Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.</p><h3 id="gradients">Gradients<a name="gradients" href="#gradients" class="md2man-permalink" title="permalink"></a></h3><p>(Available since 0.13.0)</p><p>Backgrounds also allow specifying gradient layers
+that are drawn on top of the solid color background.</p><p>First the user must define one or more gradients in the config file,
+each starting with <code>gradient = TYPE</code>. These must be added before backgrounds.</p><p>Then gradients can be added by index to backgrounds,
+using the <code>gradient_id = INDEX</code>, <code>gradient_id_hover = INDEX</code> and
+<code>gradient_id_pressed = INDEX</code>, where <code>INDEX</code> is
+the gradient index, starting from 1.</p><h4 id="gradient-types">Gradient types<a name="gradient-types" href="#gradient-types" class="md2man-permalink" title="permalink"></a></h4><p>Gradients vary the color between fixed control points:
+* vertical gradients: top-to-bottom;
+* horizontal gradients: left-to-right;
+* radial gradients: center-to-corners.</p><p>The user must specify the start and end colors, and can optionally add extra color stops in between
+using the <code>color_stop</code> option, as explained below.</p><h5 id="vertical-gradient-with-color-varying-from-the-top-edge-to-the-bottom-edge-two-colors">Vertical gradient, with color varying from the top edge to the bottom edge, two colors<a name="vertical-gradient-with-color-varying-from-the-top-edge-to-the-bottom-edge-two-colors" href="#vertical-gradient-with-color-varying-from-the-top-edge-to-the-bottom-edge-two-colors" class="md2man-permalink" title="permalink"></a></h5><pre class="highlight plaintext"><code>gradient = vertical

+.SS Introduction
 .PP
-This manual page was written by Daniel Moerner <dmoerner@gmail.com>,
-for the Debian project (but may be used by others).  It was adopted from the
-tint2 docs.
+These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface \fB\fCtint2conf\fR\&.
+.PP
+The first time you run tint2, it will create the config file in \fB\fC$HOME/.config/tint2/tint2rc\fR (This applies if you have done a clean install. Running tint2 in the source directory without doing 'make install' will not create the config file.)
+.PP
+You can also specify another file on the command line with the \-c option, e.g.: \fB\fCtint2 \-c $HOME/tint2.conf\fR\&. This can be used to run multiple instances of tint2 that use different settings.
+.PP
+If you change the config file while tint2 is running, the command \fB\fCkillall \-SIGUSR1 tint2\fR will force tint2 to reload it.
+.PP
+All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.
+.SS Backgrounds and borders
+.PP
+The tint2 config file starts with the options defining background elements with borders:
+.RS
+.IP \(bu 2
+\fB\fCrounded = number_of_pixels\fR : the corner radius
+.IP \(bu 2
+\fB\fCborder_width = integer\fR : the border width in pixels
+.IP \(bu 2
+\fB\fCborder_sides = LRTB\fR : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used. \fI(since 0.12.12)\fP
+.IP \(bu 2
+\fB\fCbackground_color = color opacity\fR
+.RS
+.IP \(bu 2
+\fB\fCcolor\fR is specified in hex RGB, e.g. #ff0000 is red
+.IP \(bu 2
+\fB\fCopacity\fR varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).
+.RE

+.RE

+.RE
+.RE
+.PP
+You can define as many backgrounds as you want. For example, the following config defines two backgrounds:
+.PP
+.RS
+.nf
+rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+.fi
+.RE
+.PP
+tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:
+.PP
+.RS
+.nf
+panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+.fi
+.RE
+.PP
+Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.
+.SS Gradients
+.PP
+(Available since 0.13.0)
+.PP
+Backgrounds also allow specifying gradient layers
+that are drawn on top of the solid color background.
+.PP
+First the user must define one or more gradients in the config file,
+each starting with \fB\fCgradient = TYPE\fR\&. These must be added before backgrounds.
+.PP
+Then gradients can be added by index to backgrounds,
+using the \fB\fCgradient_id = INDEX\fR, \fB\fCgradient_id_hover = INDEX\fR and
+\fB\fCgradient_id_pressed = INDEX\fR, where \fB\fCINDEX\fR is
+the gradient index, starting from 1.
+.SS Gradient types
+.PP
+Gradients vary the color between fixed control points:
+* vertical gradients: top\-to\-bottom;
+* horizontal gradients: left\-to\-right;
+* radial gradients: center\-to\-corners.
+.PP
+The user must specify the start and end colors, and can optionally add extra color stops in between
+using the \fB\fCcolor_stop\fR option, as explained below.
+.SS Vertical gradient, with color varying from the top edge to the bottom edge, two colors
+.PP
+.RS
+.nf
+gradient = vertical
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+.fi
+.RE
+.SS Horizontal gradient, with color varying from the left edge to the right edge, two colors
+.PP
+.RS
+.nf
+gradient = horizontal
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+.fi
+.RE
+.SS Radial gradient, with color varying from the center to the corner, two colors:
+.PP
+.RS
+.nf

+It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).</p><p>Features:</p>
+<ul>
+<li>Panel with taskbar, system tray, clock and launcher icons;</li>
+<li>Easy to customize: color/transparency on fonts, icons, borders and backgrounds;</li>
+<li>Pager like capability: move tasks between workspaces (virtual desktops), switch between workspaces;</li>
+<li>Multi-monitor capability: create one panel per monitor, showing only the tasks from the current monitor;</li>
+<li>Customizable mouse events.</li>
+</ul>
+<p>Goals:</p>
+<ul>
+<li>Be unintrusive and light (in terms of memory, CPU and aesthetic);</li>
+<li>Follow the freedesktop.org specifications;</li>
+<li>Make certain workflows, such as multi-desktop and multi-monitor, easy to use.</li>

+<h3 id="introduction">Introduction<a name="introduction" href="#introduction" class="md2man-permalink" title="permalink"></a></h3><p>These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface <code>tint2conf</code>.</p><p>The first time you run tint2, it will create the config file in <code>$HOME/.config/tint2/tint2rc</code> (This applies if you have done a clean install. Running tint2 in the source directory without doing &#39;make install&#39; will not create the config file.)</p><p>You can also specify another file on the command line with the -c option, e.g.: <code>tint2 -c $HOME/tint2.conf</code>. This can be used to run multiple instances of tint2 that use different settings.</p><p>If you change the config file while tint2 is running, the command <code>killall -SIGUSR1 tint2</code> will force tint2 to reload it.</p><p>All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.</p><h3 id="backgrounds-and-borders">Backgrounds and borders<a name="backgrounds-and-borders" href="#backgrounds-and-borders" class="md2man-permalink" title="permalink"></a></h3><p>The tint2 config file starts with the options defining background elements with borders:</p>
+<ul>
+<li><p><code>rounded = number_of_pixels</code> : the corner radius</p></li>
+<li><p><code>border_width = integer</code> : the border width in pixels</p></li>
+<li><p><code>border_sides = LRTB</code> : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used.</p></li>
+<li><p><code>background_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).</li>
+</ul></li>
+<li><p><code>border_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+<li><p><code>background_color_hover = color opacity</code> (default: same as background_color) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)</li>
+</ul></li>
+<li><p><code>border_color_hover = color opacity</code> (default: same as border_color) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+<li><p><code>background_color_pressed = color opacity</code> (default: same as background<em>color</em>hover) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)</li>
+</ul></li>
+<li><p><code>border_color_pressed = color opacity</code> (default: same as border<em>color</em>hover) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+</ul>
+<p>You can define as many backgrounds as you want. For example, the following config defines two backgrounds:</p><pre class="highlight plaintext"><code>rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+</code></pre>
+<p>tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:</p><pre class="highlight plaintext"><code>panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+</code></pre>
+<p>Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.</p><h3 id="panel">Panel<a name="panel" href="#panel" class="md2man-permalink" title="permalink"></a></h3>
+<ul>
+<li><p><code>panel_items = LTSBC</code> defines the items tint2 will show and the order of those items. Each letter refers to an item, defined as:</p>
+<ul>
+<li><code>L</code> shows the Launcher</li>
+<li><code>T</code> shows the Taskbar</li>
+<li><code>S</code> shows the Systray (also called notification area)</li>
+<li><code>B</code> shows the Battery status</li>
+<li><code>C</code> shows the Clock</li>
+<li><code>F</code> adds an extensible spacer (freespace). Has no effect if <code>T</code> is also present. <em>(since 0.12)</em></li>
+<li><code>E</code> adds an executor plugin. You can specify more than one. <em>(since 0.12.4)</em></li>
+</ul>
+<p>For example, <code>panel_items = STC</code> will show the systray, the taskbar and the clock (from left to right).</p></li>
+<li><p><code>panel_monitor = monitor (all or 1 or 2 or ...)</code> : Which monitor tint2 draws the panel on</p>
+<ul>
+<li>The first monitor is <code>1</code></li>
+<li>Use <code>panel_monitor = all</code> to get a separate panel per monitor</li>
+</ul></li>
+<li><p><code>primary_monitor_first = boolean (0 or 1)</code> : Place the primary monitor before all the other monitors in the list. <em>(since 0.12.4)</em></p></li>
+</ul>
+<p><img src="panel_padding.jpg" alt=""></p>
+<ul>
+<li><p><code>panel_position = vertical_position horizontal_position orientation</code></p>
+<ul>
+<li><code>vertical_position</code> is one of: <code>bottom</code>, <code>top</code>, <code>center</code></li>
+<li><code>horizontal_position</code> is one of: <code>left</code>, <code>right</code>, <code>center</code></li>
+<li><code>orientation</code> is one of: <code>horizontal</code>, <code>vertical</code></li>
+</ul></li>
+<li><p><code>panel_size = width height</code></p>
+<ul>
+<li><code>width</code> and <code>height</code> can be specified without units (e.g. <code>123</code>) as pixels, or followed by <code>%</code> as percentages of the monitor size (e.g. <code>50%</code>). Use <code>100%</code> for full monitor width/height.
+Example:</li>
+</ul></li>
+</ul>
+<pre class="highlight plaintext"><code># The panel's width is 94% the size of the monitor, the height is 30 pixels:
+panel_size = 94% 30
+</code></pre>
+
+<ul>
+<li><code>panel_margin = horizontal_margin vertical_margin</code> : The margins define the distance between the panel and the horizontal/vertical monitor edge. Use <code>0</code> to obtain a panel with the same size as the edge of the monitor (no margin).</li>
+</ul>
+<p><img src="panel_size_margin.jpg" alt=""></p>
+<ul>
+<li><code>panel_padding = horizontal_padding vertical_padding spacing</code> : Please refer to the image below.</li>
+</ul>
+<p><img src="panel_padding.jpg" alt=""></p>
+<ul>
+<li><p><code>font_shadow = boolean (0 or 1)</code></p></li>
+<li><p><code>panel_background_id = integer</code> : Which background to use for the panel.</p></li>
+<li><p><code>wm_menu = boolean (0 or 1)</code> : Defines if tint2 forwards unhandled mouse events to your window manager. Useful for window managers such as openbox, which display the start menu if you right click on the desktop.</p></li>
+<li><p><code>panel_dock = boolean (0 or 1)</code> : Defines if tint2 is placed into the window manager&#39;s dock. For the openbox window manager it is advised to also use a modifier for the moveButton option, otherwise the mouse click is not forwarded to tint2 (in ~/.config/openbox/rc.xml).</p></li>
+<li><p><code>panel_layer = bottom/normal/top</code> : Places tint2 into the bottom/normal/top layer. This is helpful for specifying if the panel can be covered by other windows or not. The default is the bottom layer, but with real transparency normal or top layer may be a nice alternative.</p></li>
+<li><p><code>strut_policy = follow_size/minimum/none</code> : STRUTs are used by the window manager to decide the size of maximized windows. Note: on multi-monitor (Xinerama) setups, the panel must be placed at the edge (not in the middle) of the virtual screen for this to work correctly.</p>
+<ul>
+<li><code>follow_size</code> means that the maximized windows always resize to have a common edge with tint2.</li>
+<li><code>minimum</code> means that the maximized windows always expand to have a common edge with the hidden panel. This is useful if the <code>autohide</code> option is enabled.</li>

+# TINT2 1 "2017-04-23" 0.14.2
+
+## NAME
+tint2 - lightweight panel/taskbar
+
+## DESCRIPTION
+tint2 is a simple panel/taskbar made for modern X window managers.
+It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).
+
+Features:
+
+  * Panel with taskbar, system tray, clock and launcher icons;
+  * Easy to customize: color/transparency on fonts, icons, borders and backgrounds;
+  * Pager like capability: move tasks between workspaces (virtual desktops), switch between workspaces;
+  * Multi-monitor capability: create one panel per monitor, showing only the tasks from the current monitor;
+  * Customizable mouse events.
+
+Goals:
+
+  * Be unintrusive and light (in terms of memory, CPU and aesthetic);
+  * Follow the freedesktop.org specifications;
+  * Make certain workflows, such as multi-desktop and multi-monitor, easy to use.
+
+## SYNOPSIS
+`tint2 [OPTION...]`

+
+### Introduction
+
+These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface `tint2conf`.
+
+The first time you run tint2, it will create the config file in `$HOME/.config/tint2/tint2rc` (This applies if you have done a clean install. Running tint2 in the source directory without doing 'make install' will not create the config file.)
+
+You can also specify another file on the command line with the -c option, e.g.: `tint2 -c $HOME/tint2.conf`. This can be used to run multiple instances of tint2 that use different settings.
+
+If you change the config file while tint2 is running, the command `killall -SIGUSR1 tint2` will force tint2 to reload it.
+
+All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.
+
+### Backgrounds and borders
+
+The tint2 config file starts with the options defining background elements with borders:
+
+  * `rounded = number_of_pixels` : the corner radius
+
+  * `border_width = integer` : the border width in pixels
+
+  * `border_sides = LRTB` : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used. *(since 0.12.12)*
+
+  * `background_color = color opacity`
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).
+
+  * `border_color = color opacity`
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque
+
+  * `background_color_hover = color opacity` (default: same as `background_color`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)
+
+  * `border_color_hover = color opacity` (default: same as `border_color`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque
+
+  * `background_color_pressed = color opacity` (default: same as `background_color_hover`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)
+
+  * `border_color_pressed = color opacity` (default: same as `border_color_hover`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque
+
+You can define as many backgrounds as you want. For example, the following config defines two backgrounds:
+
+```
+rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+```
+
+tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:
+
+```
+panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+```
+
+Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.
+
+### Gradients
+
+(Available since 0.13.0)
+
+Backgrounds also allow specifying gradient layers
+that are drawn on top of the solid color background.
+
+First the user must define one or more gradients in the config file,
+each starting with `gradient = TYPE`. These must be added before backgrounds.
+
+Then gradients can be added by index to backgrounds,
+using the `gradient_id = INDEX`, `gradient_id_hover = INDEX` and
+`gradient_id_pressed = INDEX`, where `INDEX` is
+the gradient index, starting from 1.
+
+#### Gradient types
+
+Gradients vary the color between fixed control points:
+* vertical gradients: top-to-bottom;
+* horizontal gradients: left-to-right;
+* radial gradients: center-to-corners.
+
+The user must specify the start and end colors, and can optionally add extra color stops in between
+using the `color_stop` option, as explained below.
+
+##### Vertical gradient, with color varying from the top edge to the bottom edge, two colors
+
+```
+gradient = vertical
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+```
+
+##### Horizontal gradient, with color varying from the left edge to the right edge, two colors
+
+```
+gradient = horizontal
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+```
+
+##### Radial gradient, with color varying from the center to the corner, two colors:
+
+```
+gradient = radial
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+```
+
+##### Adding extra color stops (0% and 100% remain fixed, more colors at x% between the start and end control points)
+
+```
+color_stop = percentage #rrggbb opacity
+```
+
+#### Gradient examples
+
+```
+# Gradient 1: thin film effect
+gradient = horizontal
+start_color = #111122 30
+end_color = #112211 30
+color_stop = 60 #221111 30
+
+# Gradient 2: radial glow
+gradient = radial
+start_color = #ffffff 20
+end_color = #ffffff 0
+
+# Gradient 3: elegant black
+gradient = vertical
+start_color = #444444 100
+end_color = #222222 100
+
+# Gradient 4: elegant black
+gradient = horizontal
+start_color = #111111 100
+end_color = #222222 100
+
+# Background 1: Active desktop name
+rounded = 2
+border_width = 1
+border_sides = TBLR
+background_color = #555555 10
+border_color = #ffffff 60
+background_color_hover = #555555 10
+border_color_hover = #ffffff 60
+background_color_pressed = #555555 10
+border_color_pressed = #ffffff 60
+gradient_id = 3
+gradient_id_hover = 4
+gradient_id_pressed = 2
+
+[...]
+```
+
+### Panel
+
+  * `panel_items = LTSBC` defines the items tint2 will show and the order of those items. Each letter refers to an item, defined as:
+    * `L` shows the Launcher
+    * `T` shows the Taskbar
+    * `S` shows the Systray (also called notification area)
+    * `B` shows the Battery status
+    * `C` shows the Clock
+    * `F` adds an extensible spacer (freespace). You can specify more than one. Has no effect if `T` is also present. *(since 0.12)*
+    * `E` adds an executor plugin. You can specify more than one. *(since 0.12.4)*
+    * `P` adds a push button. You can specify more than one. *(since 0.14)*
+    * `:` adds a separator. You can specify more than one. *(since 0.13.0)*
+
+    For example, `panel_items = STC` will show the systray, the taskbar and the clock (from left to right).
+
+  * `panel_monitor = monitor (all or 1 or 2 or ...)` : Which monitor tint2 draws the panel on
+    * The first monitor is `1`
+    * Use `panel_monitor = all` to get a separate panel per monitor
+
+  * `primary_monitor_first = boolean (0 or 1)` : Place the primary monitor before all the other monitors in the list. *(since 0.12.4)*
+
+![](images/panel_padding.jpg)
+
+  * `panel_position = vertical_position horizontal_position orientation`
+    * `vertical_position` is one of: `bottom`, `top`, `center`
+    * `horizontal_position` is one of: `left`, `right`, `center`
+    * `orientation` is one of: `horizontal`, `vertical`
+
+  * `panel_size = width height`
+    * `width` and `height` can be specified without units (e.g. `123`) as pixels, or followed by `%` as percentages of the monitor size (e.g. `50%`). Use `100%` for full monitor width/height.
+      Example:
+
+```
+# The panel's width is 94% the size of the monitor, the height is 30 pixels:
+panel_size = 94% 30
+```
+
+  * `panel_shrink = boolean (0 or 1)` : If set to 1, the panel will shrink to a compact size dynamically. *(since 0.13)*
+
+  * `panel_margin = horizontal_margin vertical_margin` : The margins define the distance between the panel and the horizontal/vertical monitor edge. Use `0` to obtain a panel with the same size as the edge of the monitor (no margin).
+
+![](images/panel_size_margin.jpg)
+
+  * `panel_padding = horizontal_padding vertical_padding spacing` : Please refer to the image below.
+
+![](images/panel_padding.jpg)
+
+  * `font_shadow = boolean (0 or 1)`
+
+  * `panel_background_id = integer` : Which background to use for the panel.
+
+  * `wm_menu = boolean (0 or 1)` : Defines if tint2 forwards unhandled mouse events to your window manager. Useful for window managers such as openbox, which display the start menu if you right click on the desktop.
+
+  * `panel_dock = boolean (0 or 1)` : Defines if tint2 is placed into the window manager's dock. For the openbox window manager it is advised to also use a modifier for the moveButton option, otherwise the mouse click is not forwarded to tint2 (in ~/.config/openbox/rc.xml).
+
+  * `panel_layer = bottom/normal/top` : Places tint2 into the bottom/normal/top layer. This is helpful for specifying if the panel can be covered by other windows or not. The default is the bottom layer, but with real transparency normal or top layer may be a nice alternative.
+
+  * `strut_policy = follow_size/minimum/none` : STRUTs are used by the window manager to decide the size of maximized windows. Note: on multi-monitor (Xinerama) setups, the panel must be placed at the edge (not in the middle) of the virtual screen for this to work correctly.
+    * `follow_size` means that the maximized windows always resize to have a common edge with tint2.
+    * `minimum` means that the maximized windows always expand to have a common edge with the hidden panel. This is useful if the `autohide` option is enabled.
+    * `none` means that the maximized windows use the full screen size.
+
+  * `panel_window_name = string` : Defines the name of the panel's window. Default: 'tint2'. *(since 0.12)*
+
+  * `disable_transparency = boolean (0 or 1)` : Whether to disable transparency instead of detecting if it is supported. Useful on broken graphics stacks. *(since 0.12)*
+
+  * `mouse_effects = boolean (0 or 1)` : Whether to enable mouse hover effects for clickable items. *(since 0.12.3)*
+
+  * `mouse_hover_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjusts the icon color and transparency on mouse hover (works only when mouse_effects = 1).` *(since 0.12.3)*
+
+  * `mouse_pressed_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjusts the icon color and transparency on mouse press (works only when mouse_effects = 1).` *(since 0.12.3)*
+
+  * `autohide = boolean (0 or 1)` : Whether to enable panel hiding when the mouse cursor exists the panel.
+
+  * `autohide_show_timeout = float` : Show timeout in seconds after the mouse cursor enters the panel. Use '.' as decimal separator.
+
+  * `autohide_hide_timeout = float` : Hide timeout in seconds after the mouse cursor exits the panel. Use '.' as decimal separator.
+
+  * `autohide_height = integer` : panel height (width for vertical panels) in hidden mode.
+
+### Launcher
+  * `launcher_item_app = path_to_application` : Each `launcher_item_app` must be a file path to a .desktop file following the freedesktop.org [specification](http://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html). The paths may begin with `~`, which is expanded to the path of the user's home directory. If only a file name is specified, the file is search in the standard application directories (`$XDG_DATA_HOME/applications`, `~/.local/share/applications`, `$XDG_DATA_DIRS/applications`, `/usr/local/share/applications`, `/usr/share/applications`, `/opt/share/applications`).
+
+  * `launcher_apps_dir = path_to_directory` : Specifies a path to a directory from which the launcher is loading all .desktop files (all subdirectories are explored recursively). Can be used multiple times. The path may begin with `~`, which is expanded to the path of the user's home directory. *(since 0.12)*
+
+  * `launcher_background_id = integer` : Defines which background to use.
+
+  * `launcher_icon_background_id = integer` : Defines which background to use for icons.
+
+  * `launcher_padding = horizontal_padding vertical_padding spacing`
+
+  * `launcher_icon_size = integer` : The launcher icon size, in pixels.
+
+  * `launcher_icon_theme = name_of_theme` : (Optional) Uses the specified icon theme to display shortcut icons. Note that tint2 will detect and use the icon theme of your desktop if you have an XSETTINGS manager running (which you probably do), unless `launcher_icon_theme_override = 1`.
+
+  * `launcher_icon_theme_override = boolean (0 or 1)` : Whether `launcher_icon_theme` overrides the value obtained from the XSETTINGS manager. *(since 0.12)*
+
+  * `launcher_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjusts the icon color and transparency.
+
+  * `launcher_tooltip = boolean (0 or 1)` : Whether to show tooltips for the launcher icons.
+
+  * `startup_notifications = boolean (0 or 1)` : Whether to show startup notifications when starting applications from the launcher. *(since 0.12)*
+
+### Taskbar / Pager
+
+  * `taskbar_mode = single_desktop/multi_desktop`
+    * `single_desktop` : Shows a normal taskbar listing the tasks running on the current virtual desktop (also known as 'workspace');
+    * `multi_desktop` : Pager like capability. Shows multiple taskbars, one per virtual desktop, with which:
+      * You can drag-and-drop tasks between virtual desktops;
+      * You can switch between virtual desktops.
+
+  * `taskbar_hide_if_empty = boolean (0 or 1)` : If enabled, in multi-desktop mode the taskbars corresponding to empty desktops different from the current desktop are hidden. *(since 0.13)*
+
+  * `taskbar_distribute_size = boolean (0 or 1)` : If enabled, in multi-desktop mode distributes between taskbars the available size proportionally to the number of tasks. Default: disabled. *(since 0.12)*
+
+  * `taskbar_padding = horizontal_padding vertical_padding spacing`
+
+![](images/taskbar_padding.jpg)
+
+  * `taskbar_background_id = integer` : Which background to use
+
+  * `taskbar_active_background_id = integer` : Which background to use for the taskbar of the current virtual desktop.
+
+  * `taskbar_hide_inactive_tasks = boolean (0 or 1)` :  If enabled, the taskbar shows only the active task. *(since 0.12)*
+
+  * `taskbar_hide_different_monitor = boolean (0 or 1)` :  If enabled, the taskbar shows only the tasks from the current monitor. Useful when running different tint2 instances on different monitors, each one having its own config. *(since 0.12)*
+
+  * `taskbar_always_show_all_desktop_tasks = boolean (0 or 1)` :  Has effect only if `taskbar_mode = multi_desktop`. If enabled, tasks that appear on all desktops are shown on all taskbars. Otherwise, they are shown only on the taskbar of the current desktop. *(since 0.12.4)*
+
+  * `taskbar_sort_order = none/title/center` : Specifies the sort order of the tasks on the taskbar.  *(since 0.12)*
+    * `none` : No sorting. New tasks are simply appended at the end of the taskbar when they appear.
+    * `title` : Sorts the tasks by title.

+  mouse_scroll_down = iconify
+```
+
+The action semantics:

+  * `execp_background_id = integer` : Which background to use. *(since 0.12.4)*
+
+  * `execp_centered = boolean (0 or 1)` : Whether to center the text. *(since 0.12.4)*
