Currently, when I import an image into canvas, and then scale it, the scaling values are kept only until the command is exited. Then I calibrate, do some sketching, and realize this won't work. I go back to re-scale my image, and all the scale values are set back to 1, and not referenced to the original size. This requires me to keep track of all the scaling modifications I may have done on the fly.
It would be EXTREMELY useful for the scaling of the canvas to always reference the original image input, then display the current scale relative to the original image size. This way I don't have to keep track of all my steps along the way, it's just all relative to the starting point.
