I'm looking to try it out, but on my fresh Ubuntu Gnome 14.04 install the gnome-tweak-tool extension tab is telling me 'Extension does not support shell version'. I don't see it mentioned on the github project. What distro and version of gnome shell did you intend this for?
I'm using an old laptop, so I can reinstall whatever; just want to get this working to test out! Thanks for your hard work!
