And it arrived just few hours before the 3.8 beta release! However Shell will ask probably some more time before “features freeze” as there are more exciting things to come.
Categories removed, application groups came, there is now a view for frequent use applications, and many new animations added. There is still some work going on and maybe the final release will be a bit different than what I am showing now. http://worldofgnome.org/the-new-gnome-shell-interface-arrived/
