One of the things I do a LOT is outline a circular object (in a photo) using the line/curve tool in a separate layer so that I can select the circular thing or everything else. Hope that made sense. Anyway, the thing is not exactly a circular and the line/curve tool works great but it would be nice to have a shape tool that would draw a circle that could be sized/positioned and slightly deformed using nibs (or nubs or whatever) similar to the line/curve tool. Is there a way to do that with the built in shape tool? Or is there a plugin?
