Provide a means of setting precise size and position in a scene
One of the strategies for drawing a color stock image is to use the original stock image (already drawn) and overlay an imported colored version of the image. But the size and position of the overlay has to be precise for this to work properly. Using the current UI this an approximate and frustrating task. I would think there must already be some scheme being used to determine size and position - if we could have access to those numbers, we could easily and perfectly match the overlay. This would have positioning benefits in other ways as well, like duplicating elements across scenes.
