Good to see the're progressing to get back to Gnome 2
After a few years of tweaking, many Unity features that made it different from Mate/Gnome/KDE are gone: scopes, search bar, window menus at the top, tool bar at the left... it seems to me that Unity has been a long diversion to reach the same destination at the end. Or are there still unique Unity features that can't be replicated easily in Mate/Gnome/KDE?
(note: Gnome is also experiencing the same evolution. From the original, radical Gnome 3 desktop a lot of features have been added so you can end up with a desktop very similar to Gnome 2)
