If you pick any random GNOME user, they would give you a different “Top 5” list.
I install and try quite a few of them whenever I come across an article or a video recommending one or other extensions. However I don’t keep them all.
If I were to pick my “Top Five”:
- dash-to-panel
I use it at top to replace GNOME’s own topbar. It is quite versatile but I configure it minimally.
-
Blur my shell
-
Custom Hot Corners -Extended
-
Clipboard History
-
User Themes
However I do use a few more.
