In source mode, when I collapse the right rail, I get two scrollbars (the thing you were trying to avoid when removing the option to centre the line you're editing). I'm using firefox. A screenshot of this and other issues can be found here, my comments are in red. EDIT: sorry, just seen this has been brought up by User452 below.
