The popular Unity Revamped PPA has stopped working once again a while back, but there's a new PPA that adds the same features to Unity along with some extra ones such as the Unity Touch Launcher icons.
The new Unity Revamped PPA, maintained by Garhuy, is only available for Ubuntu 12.04 LTS and adds the following features to Unity (with Compiz):
- re-added Dodge Windows behavior;
- minimize on click for Launcher items;
- option to enable/disable the Workspace Switcher icon on the Launcher
- Ubuntu Raring launcher assets (the new BFB icon - the button used to open Dash, workspace switcher, etc);
- Ubuntu Touch Launcher icons.
