I'm fine with the dialogs layouts.
Not paying much attention to the code, not a fan of favorites :)
Just mentionning that ReadCollection is rather unoptimized (#6054 (comment)), as it reread the full collection.lua each time we call one of its functions. From a quick look at this PR, it looks like it will be done once each time we display such a dialog, so it's bearable - if it is really just once.

Yes, and when editing Favorites it flushes on every single operation (add, remove, sort). Must be fixed (some day).
