I may be in the minority, but I actually like Gnome 3...it allows me to work in a pattern similar to what I've grown accustom to on the Mac.
One question I had, though, is when you switch into the "activities" overview screen and all of your windows are shown in an Expose-like fashion, is there any way to use the keyboard to select which window you want or is this only possible using the normal alt-tab shortcut when NOT in the activities screen?
Seems like it would be fairly obvious to allow the user to use the arrow keys and enter to select a window in the activities overview screen, no?
