Just got a steam deck and immediately checked out the desktop mode, and I was somewhat surprised to see KDE and pacman as opposed to GNOME and apt, I have nothing against the former though a strong preference for the latter, anyone know why Volvo went in this direction?
ElementaryOS sounds like a perfect fit for you, if you haven’t tried it already. Superb gesture support and consistent UI across all built in apps
That said, a lot of the gesture support has been implemented in Gnome and KDE now anyway, particularly partial gestures which previously had very poor support IIRC
