Some way to rotate the whole canvas. I have groups of ideas around my central idea, either radially oriented, or facing the cardinal directions. To add a new bit to the stuff that is already there, I have to view my prezi until I get to the correctly oriented text, then switch to edit to put the new stuff in. If I could rotate the whole canvas in edit mode, that would be great.
Press and hold 3 and 4 (the number keys) to rotate.
