What makes Linux appealing to me is the extent of customizability, but I didn’t find many answers when looking up with desktop environment is them most customizable. Some say KDE is most customizable than say, Gnome, but doesn’t Gnome support CSS customization while KDE doesn’t?
KDE if you want to just configure stuff. Gnome if you want to code or manually style stuff.
Doesn’t gnome change their APIs all the time between minor versions, so themes and plugins have to be constantly rewritten?
Yes, that too. I should have said want to code stuff…and continue to maintain it…
I used to use gnome and I am heavily into customization. I gave up using gnome as they would constantly change things often for no real reason that whimsy, breaking previously working scripts, extensions and so on so I stopped using it. Its fine if you want to customize the basics like wall paper but I really wouldn’t bother for in-depth customization. Not because it isn’t possible, but because maintenance of it is a PITA.
This. Or a window manager to code the whole thing.
