- Menu detects what is on and applies only the changes: SteamOS conversion, SteamOS theme, Steam Deck/Machine icons, single user mode, and Steam Machine support (only on Fremont hardware) - Everything is reversible: KDE settings go through an undo journal (lib/state.sh), system files are restored from their backups - Steam Machine support: LED driver, udev rule giving the user the LED files, steamos-manager for Steam's hardware settings; OpenRGB dropped - Edit Plasma files only while plasmashell is stopped so it can't overwrite them - README and AGENTS.md describe the menu, the component model and the test environment
