Allow the desktop grid to be disabled
The desktop grid is useful, but it can also limit the ability to place a window exactly where a person would like to. The grid covers a large area directly in front of the normal view which is where most of the gaming or visuals take place. It pulls the windows location and rotation into the center. I usually will try to place my media player or web-page at an angle and slightly away from the center of my view, and then pin them down. The grid makes this placement difficult to do.
