Feature request: White Board - Sketch, Draw, Doodle

Sometimes I just want to circle something quick and fast. I prefer things a little more loose like I was drawing on a white board. Everything is so systematically snappy it drives me insane! If for example I need to draw an outline of a dead body, my choices are square, circle, diamond, and arrow. Otherwise I have to precisely draw the curvature of a flight plan to Mars and back.
