I'm using Ubuntu 12.04 with Gnome3 (i didn't remove Unity, just switched while logging in).
I love the feature of hitting the top left corner of the screen to see an overview of my open windows and desktops, but the "Favorites/Currently Open Programs" Dock on the Left really annoys me because I already have a Dock at the left side of the screen (AVN) and a Bar at the Bottom of my screen which shows me which windows i have opened. So I have no use for this Dock.
How can I disable it while keeping the rest of this cool "hit top left corner" thing? :)
