But one thing...
My PPA has a lot of bleeding edge packages without recommended "fool-proof"... :P
So this is the "trial step" for it:
* gnome-shell 3.1.91 or higher.
- Download my package from launchpad: Link
- Install via "sudo dpkg -i FILE_NAME".
- Activate this extension via gnome-tweak-tool.
Have a nice day! :)
