On this note, perhaps a future version of PD could include some rudimentary drawing features, such as simple shapes (square, circle, polygon, arrows, etc). This feature could be used very effectively in conjunction with the masking tools, too! (Imagine using the aforementioned polygon tool to draw a shape around your actor and make it solid green so you can chromakey it out). The possibilities are endless!
