Before Gnome3, Ubuntu emulated middle click with 3 fingers tap on the touchpad.
After Gnome3, it was used to drag windows (and maximize/restore). I missed the very useful middle click gesture, but at least I had something in return.
Now I just upgraded to 13.04, and I have neither.
OK, just noticed, now that I have more than one window open, it's the same as Alt+Tab (once). So I can just alternate between two windows.
Is there any way to have either of the old behaviors? Ideally the middle click simulation? I consider that one to be the ultimate feature for the 3 finger touchpad gesture, as most laptops only have two physical buttons.
