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
One of my favourites that I haven’t seen mentioned is the Todo.txt extension.
It adds a todo list in the tray synced to a couple of files (that I store in Nextcloud). I add things I need to do to the list, and I also play with the settings so it colours by priority and sorts by priority.
I also use the ntodotxt app on my phone to sync items. The app is fine but I really like the gnome extension, very handy.
