@tio @dark That’s because you expect these apps to not look fragmented. They always did and they always will.
I use GNOME apps only, and a few that aren’t specifically made for it. My experience is 100% better today than it was 10 years, or 17 years ago. When I use KDE, I use KDE apps only. Use apps for your desktop. There is no coherency on Linux, there is DE coherency. You’re expecting something that never existed and will never exist.
