This would be terrible. Gnome and KDE have pretty conflicting ideologies. Gnome is super opinionated and Mac-like minimalist. KDE is all about user choice.
If they'd collaborate it would end up something in the middle which would suit nobody.
...you can't compare minimalism/configurability in this way
Ed: one minor (but somewhat understandable annoyance) is the lack of a free/reserved for users modifier key. Macos with the adoption of bsd uses both command, option and control (even though it uses command for core things like copy/paste). The windows/super key is a blessing on Linux pcs - as it generally can be used for just that - window management).
I know some rebind caps lock as a super (ed2: I mean "hyper", I think) (aka ALL THE MODIFIERS) key on Mac - but that leaves control in the wrong place :/
Maybe there's no RSI in Palo Alto?
The problem with this is that Mac, unlike Gnome, actually works. Gnome just has weird holes where old functionality was removed (like application menus!) and never replaced.
Yeah. Without proper window management, middle click and other things I need 3rd party apps for.
