What’s new on Gnome 3 (getting around): Besides its User Interface, I managed to navigate between workspaces via pressing Ctrl-Alt (Up/Down) Arrow Keys. The more you used other workspaces it automatically expands and remove other workspaces if it’s not needed. Very much happy moving to Gnome (in my opnion) because I can quickly search apps and response more quickly in the default Unity GUI of Ubuntu 12.04 LTS Desktop.
