Visual UVW Editing

I would like to see the texturing process made easier a little bit by adding a visual UVW editing interface. It would just be a display of the texture in question, with an outline of the object to represent the borders of the UVWs. The builder could then move, scale and rotate the UVWs around on top of the texture to align his/her texture just right. A simple change, I think, that would help to ensure quality output.
