Agree, if they had the flatpak extensionmanager installed by default that would be cool. But dash to panel is still much worse, way less tray icons fit there, the app menu may be inconsistent.
Also I have to say that the complete lack of .desktop entry modification makes distinguishing flatpaks from native apps, or creating entries with slightly changed parameters, appending arguments like “force X11” etc. very hard.
Nautilus may be solid but it lacks so many features and I still dont know how to deal with it. If you know how to add a real “delete” entry that would be great.
I also think the traditional decorations extension is gone? But I dont know.
Didnt know you could change the UI density, thats cool.
