"Vast majority" does not describe that class of functionally:) I do
not insist on terms but I think we understood each other.

It does, in both KDE and GNOME. But it is optional - some people still
prefer it the windows way.

This is detail of implementation IMHO - but in general I see your
point. Yes, race conditions are possible. Checking for the active
window would allow to resolve some of them (not allowing inactive
windows to change the layout directly) - but I have to think more
about it.

Thanks for the insightful comment,
