I know about that mockup, but:
* we should allow users changing the order of the added layouts
* the AddLayout dialog as a reaction on clicking the Secondary Layout
icon is problematic (the same issues we have with the current one)
* more things answered below applies to this mockup

The problem now is that the AddLayout dialog lists layouts prefixed with
languages they are related to (and there are many layouts for which this
is really useful). But since some layouts have multiple related
languages, listing some of the layouts multiple times would result in a
really, really long list (even without duplicates there are IIRC over
600 items in it) bringing performance, clarity and generally UX
problems. However, the result is that e.g. the Belgian layout is listed
as Dutch, because that's the first language we iterate over when getting
all layouts. And people then struggle finding it in the list because
they search for the Belgian layout, not 'Dutch (Belgian)'.
Thus we should do the listing two-level: language --> layout

Well, I'm for a treeview and this expanding since January 2012 when the
first discussion about these things happened. Have a look at your
summary of our discussion from that time:
Has something changed? Based on this I thought a two-pane selection
would be better from the accessibility and clarity perspectives and also
it would fit in the Anaconda's patter of using two-pane selection for

That's the same bar (widget) that is used in my mockup, just with a
different size and position (left in custom partitioning, center in my

That would mean Gtk will likely resize and reorder half of the GUI
because there would be a new "column" in the ListBox. We could hack this
around, however, by setting some size request for the ListBox.

Same issue here, I'm really not sure Gtk is prepared for this "hover to
reveal" things. As a practical example -- I had to make column headers
visible with the name of the column with the right arrow set to ""
because otherwise the arrow didn't show.

Not sure hitting quite a tiny arrow would be usable for all users.

To allow such testing we would have to replace the X server's runtime
configuration with the currently selected layout, let user test the
layout and then, when they leave the testing box, restore the X server's
runtime configuration to the original state. That would be confusing for
users, I'd say, and it would cause 3-5 seconds long UI hangs (changing X
server's runtime configuration is not a cheap action). That's why I'd
like to provide testing of the current configuration, i.e. added layouts
and layout switching.

Don't know if icon on the left is better then icon on the right. But
when I tried using our "selected" icon from the disk selection, it was
so tiny that it was hard to recognize. That could be solved, but still I
think radio buttons are more common and better understandable.

Same issues with these appearing buttons as above.
Another problematic thing is that when the spoke appears, there will be
two lists without a single button. Don't know about other users but I'd
struggle guessing what is expected from me as a user if somebody just
gives me two lists. Should I drag&drop layouts or what?
I'd suggest following:
* have two lists -- one with languages expanding to layouts and one with
* arrow buttons for moving layouts "between" those lists (i.e.
* preview buttons under both lists
* arrow buttons for changing order of the added layouts
* layout switching configuration below the list of added layouts
* testing area at the bottom of the spoke
* "is default" icon or radio button either on the left or on the right
of the the default layout
* double-clicking a non-added layout adds it
* double-clickign an added layout makes it the default one
* drag&drop working? (RFE)
* tooltips over the "Default" column, icon/radio button and layout
explaining that it will be the only VConsole keymap configured
