I think it is not obvious what "rotate left" and "rotate reight" means. Actually, it should be "rotate clockwise" or "rotate counter-clockwise"...Any way, that's not the important thing.
Three clicks are needed for rotating and image (click for menu, click in "Advance image commands", and click in the rotate command...). I think this is a basic action for many users and should be more easy to do.
I propose two posible solutions:
-Add buttons to rotate (in display view, at least)
-Gestures (by clicking and dragging the image would be rotated... as iPad does, I think)
What do you think? It is posible to include this innovative feature (gestures)?
