Re: Do all the existing shell extensions in Gnome 3.6 work in 3.8?
if you install gnome-tweak-tool you can actvate the installed extensions , it gives you a list . If you go to the bottom and click on "get more extension" it will take you to https://extensions.gnome.org/ and show you what other extensions will work with the gnome-shell version you have installed ( I saw 4 pages of them ) I installed some from there and they work .
if it ain't broke you haven't tweaked it enough
