I moved to KDE for better gaming support, but I really dislike the condensed look of everything in the settings app, discover, and most of all in Dolphin.
Are there any discrete, simple, clean themes that have more padding ? I like how GNOME looks but I really dislike their slow development for gaming related stuff.
try KvLibadwaita. otherwise, you can install gnome apps on plasma and use those instead of kde apps.
