Allow maker pen objects to connect to certain parts of the hand in costumes, like where the creases are located on the hand all move differently, but allow the parts of a costume to connect to them, so your costume isn't stiff or flat, it will move along with the hand, like in the picture below, each outlined part a maker pen object for a costume to connect there, and move along with it, i think this would make a huge difference of what people can do with costumes.
