Character and Prop Line Width Adjustment
I was using a character in a video, an image of a woman sitting. Her image was in a much finer line width stroke than the scene and props she was shown with. As I resized her to a smaller image to fit a prop her line width decreased proportionately. She was pretty much invisible by the time she was sized correctly.
It would be very helpful and desirable to be able to increase the line or stroke width for characters. You do permit changes to their opacity, but since they are all starting at 100% there is no room for improvement there.
