I was wondering, although it might have been suggested, that if we could have an image we could pin up to the side of the screen for reference/inspiration. Unlike tracing, it will just be an image that stays on top and floats (be able to move about).
I think this could be useful if you are drawing the same subject but in a different position/angle etc. Also being able to capture the colours would be very useful. I don't have to keep switching to a photo view in another program this way.
