- Setting 'id' (which changes the Global Storage key that
gets used) is a kludge when the existing module-instance
name can be used instead -- and **was** already used, as
a fallback when 'id' is not set. There's no point in having
two places to set a particular name.
- Rip out the docs for 'id' as well.
- Add documentation on the difference between single-selection
(the QML implementation) and model-selection (what the Widgets
version does).
- in legacy mode, *id* can have an effect and leads to
"packagechooser_<id>"; if unset, uses the the module
instance id instead, still as "packagechooser_<instanceid>".
- in packages mode, *id* is not used and only the whole
module Id (generally, "packagechooser@<instanceid>")
is used, but in packages mode there's no need for other
packages to mess with GS settings for this packagechooser.
- don't pass the item IDs to packages module, use the
packages lists for each item
- document the item list in more detail (including the packages member
and new install-method item)
In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
- Since the package chooser might be used more than once, or for
more specific items than "Packages", introduce a way to provide
specific strings for display.
- The only string needed is the ViewStep name, since the item with
id "" can be used for the no-selection item.
- Use *appstream* as key in one of the items for the package-
chooser to load data from the AppStream cache in the system.
- Usable for some applications; for DE-selection not so much.
- Currently unimplemented.
- Using id's as keys in a map orders them indeterminately -- in
practice, alphabetically by key. Switch to a list form so that
the products stick to the order they have in the config file
(which means distro's can list "preferred" versions at top).
