yea, i tried kubuntu-desktop, but all the shortcuts like switching program with alt + TAB is not activated, nor is aft + F4 and somehow Brave logs me out everytime on KDE when i close Brave, very weird. Though is there more customization on ZorinOS than just the whole look?
Yes. Zorin brings the Taskbar, Startmenu and other Gnome Extensions. To these come the Themes and Icons. They deliver LibreOffice Updates, too. And there would be Zorin Appearance where You can set up the Desktop Layouts and the Colors or choose Your own Style Elements.
