Would love this addition. The ability to make things look more sketchy would be great at earlier stages of design. Often we throw things in a filler or in-development, and because the rest of the rendering looks so polished, we get complaints when the finished product doesn't look like the rendering we showed at SD. Would love the ability to have something like this with the click of a button and eliminate the postprocessing we have to do in illustrator or photoshop to make things look more conceptual.
