I’ve been a Gnome fanboy for years, after initially disliking the shift between 2 and 3.
I dipped into Plasma when 6.0 came out and I’m mad that I didn’t try sooner.
It’s the exact opposite of your experience, about Gnome not having scroll wheel speed adjustment. “Wait, other DEs had figured this out? For how long??”
There was so much I’d just put up with, thinking that if Gnome hadn’t figured it out, nobody had.
KDE is something I can set up on friends’ computers and walk away, confident that it wouldn’t give them any trouble.
