The current rotation system only allows for 8 or 12 different rotations.(my maths are terrible).
A good rotation system would really be, including the current rotations, if you hold "R" the object you are rotating will follow the mouse, or you could type in the exact decrees to which to rotate the character.
This would increase the diversity one model could provide. And yes I know it is possible to offset the model so it only does rotate 15 degrees, This would be faster.
