oh yep, should’ve clarified, /system.yaml’s, as the name might suggest (lol), for system-wide config only, and GNOME just so happens to support system-wide config (dconf and gsettings overrides); we used to have a utility for declaring config for individual users akin to home-manager in blendOS v3, but dropped it with v4 since that wasn’t used much; still might make a return though :)

thank you for your support! :)
