The closest I ever got was just using two controllers. I really hope Valve will make a new controller for the Steam Deck and it’s able to be split in half.

There are lots of useful programs that can be installed through the Discover Software Center as flatpacks. Some of my favourites are Gimp, Kdenlive, Kodi, Blender, LibreOffice, CoreKeyboard, Discord, Flatseal, KDiskMark, MComix, Calibre, and Pidgin.

Some fun ones are Space Cadet Pinball, Prism Launcher (for Minecraft) and Heroic Games Launcher (for GOG, Epic Games and now also Amazon Games).
