please add ability to nudge faster and/or a specified distance with arrow keys for smaller increments and shift + desired arrow key for greater distances (e.g. like 10px per nudge with shift key vs. 1px per arrow key only) — additionally would be nice to specify the nudge increments in preferences (i.e. specifying the unit like pixels, points, ems, inches, whatever and the number of units like 1, 3, 5, 7, 10, whatever). thanks in advance!
