I have a minor transformation box suggestion. Could the rotate "hotspot" be a wee bit larger or further away from the corner? I find especially when using a pen/tablet that the resize and rotate icon/hotspots flip a lot back and forth and it takes a little effort to get the one you want. I think if the rotates hotspot was a little further off each corner you would be able to get into the general area and spin it around quickly without too much effort. To resize, would be just to get in closer to the actual corner...
