I'll definitely be checking KDE out after last using it years ago! (no slight on KDE, just my use-case changed and I don't have much use for full DEs on Linux).
Seems osnews.com goes back years and years although I can't say I noticed it until the Asahi kerfuffle and I wasn't impressed with what I saw. Still, not many blogs have that kind of longevity.
It sadly doesn't quite work right on KDE. You can get close: you can show an application launcher, or a exposé-like window overview, or a pager, but you can't show all of them at once in a way that's easy to work with between like Gnome does.
Heck, even Gnome regressed Gnome 40, as you don't get the vertical desktop overview any more. At least there's shell extensions that let me get Gnome 3's behaviour back.
It's a real pity, because I like KDE, and definitely the KDE apps, more, but the Super-key overview is no hard to quit.
I'm a new user of KDE and I like it, but sometimes it's just tiering to try to set it up like I would like.
A simple exemple, Meta+Mouse_scroll to change the desktop.
By default in Gnome and I've no idea with KDE (for know, maybe you have a tip for me???? ;) ).
