I was looking thru the FAQ, suggestions, handbook, etc. and didn't see any mention of this so I hope I'm not just blind and suggesting a feature that already exists lol. Anyway, I rarely use the draw feature but when I do it's usually to clean up an image after I cropped it. For example, I'll import an image with multiple characters but only want to reference one of them, so I crop it down to just that character and draw over the remnants of the others surrounding them just to cut down on distractions. Thing is i would do this way more often if there was a way to keep my lines within the image...I end up having to fiddle with it trying to draw a straight line right up against the edge. I guess this is kinda a niche issue since it comes from me wanting to keep everything looking clean and organized, but still i think it would open up this feature's usability pretty significantly.
