Not yet. I'm a GNOME user and I also use Plasma 5 for customization (idk if 6 is compatible with old themes and stuff). Though I want to try it and see if there are any performance improvements
I’ve tried running KDE Neon in a VM and it seems that all Plasma 5 widgets and themes aren’t compatible so they don’t show up in search. Kind of a bummer.
Thats just how it is. There are tons of extensions that also dont work in Plasma5 but its not sorted. There are porting guides for extension developers in the KDE lemmy
