We have a list of windecos to select from and then below it, barely separated from it - is a UI that does a completely different thing. This may already confuse users into mistaking the button config UI for just another windeco preview if they don't look closely enough, and the new situation with a button expanding into the full UI when the window is resized might just add to the confusion ("jumpy" UIs should be avoided if possible, as they are less predictable).

I just tried with tabs and that is challenging. We have two options:
* move the tabs outside with decoration list on one and buttons on other
* have the quick part being the tab view

The first one causes the problem that we have two QtQuick view with all the nastyness this brings including possible breakage. I expect this to be so bad that I did not even try.

The second makes the UI strange by still showing the search field when being on the buttons and even more: the layouts break when switching tabs. See http://paste.opensuse.org/77641900

I can give a try to the option 1 but I doubt it will work.
