I use the following:

  • AppIndicator/KStatusNotifierItem support(Most apps rely on trays so this is useful)
  • Clipboard Indicator(I wish Gnome natively had this but its fine Cinnamon doesnt to)
  • Desktop Logo
  • gtile(I want a tiling window manager like thing for Gnome i heard its faster)
  • Quick Settings Audio Panel
  • GSConnect (Looks better,Integrates better with GNOME)
  • Alphabetical App Grid
  • Arch LINUX Updater
  • Removable Drive Menu

i created this cause i wonder who uses Gnome on the Fediverse without plugins and maybe Gnome Tweaks and i may find some useful extensions here
Also Cinnamon users may count aswell but idk this is primary focused on GNOME
i also like my GNOME almost stock
