Indeed, an alternative to virt-manager would be more than welcome. "What, you want to search the XML for a text string? Why would you want to do that? Undo? That's crazy talk!"

I had hoped KDE was over the K-named thing, but I guess not. At least Karton is better than Kvirt-manager.

Karton is German for cardboard and is often used as short for Karton Schachtel (cardboard box), so I guess it's about boxing. A lot of the time the German word for something is similar to the English word just with a K instead of a C. And I think a lot of KDE developers are German. So that makes sense to me.

Plasma's shell is in Kirigami and Qt Quick, it couldn't be more consistent and integrated into the DE than that.

Yeah, that must be why plasma has always felt so janky to me... Even just simple stuff like simple menu launcher or task manager I can always get into an unexpected state or weird inconsistent behaviour...

I like KDE apps though, usually end up using those together with something like lxqt or xfce

That's the QML render jank that requires a commercial Qt license to avoid. But hey at least you get to write JSON-like syntax to build apps.

I think Qt Quick is a pretty generic level, you can make a lot of different interfaces with it. Kirigami is more specific.
