"Only one window per application" -> "Show single icon instead of windows" (maybe? SHould definitely start with a verb though, to match the previous one)

Do we need Main and alternative which are basically just the same thing twice? There will be of course people who make use of it in their workflow

Maybe there would be a possibility to make this also a gridview kcm showing prviews of the switchers? Will not work because of the kwin effects switchers.

@davidedmundson I would like to get this task assigned to me

What do you want to do exactly?

@abetts I intent to rewrite the UI of tabbox kcm in QML/Kirigami. I intent to follow this image as reference:- https://phabricator.kde.org/M112/391/

Rewriting it 1:1 as it is without regressions would be a good start. But sure, there are ways to improve it further from there :)

By the way, actual tabbox implementations could use some love too. They are way too complex on C++ side, and way too verbose with lots of duplicated code in QML.
