Disabling Users
I use Gnome 3 daily, and I hate it!! Simple tasks like shutting the computer down require an unconscionable number of clicks and dialogs. Context sensitive right click menus don't exist in important areas such as the open applications bar at the bottom. The "hot corner" is an abortion, sometimes changing the view instantly, and others stubbornly refusing to react. The absolute worst "feature" is the removal of the desktop as a workspace. I can no longer put folders, links to files, and URLs there for quick reference and to organize projects. Now it is just a useless empty space filled with thumbnails. If it were not for Gnome Shell Extensions, it would be completely unusable. It is the worst Linux desktop yet!
