I have the chimp, and I believe they cheat a bit by making the toes one piece & including a "toe thumb" for grasping poses. I don't think the feet of quadrumanes (primates with thumbs on their feet) are as flexible as the hands (more than ours, certainly, but the limits would be less than their hands) Still, it would be nice if the BodyParts list were built like the Heirarchy window with a "+" to expand children of a parent. And I've always thought it'd be easier if you could make a part invisible/visible from that list too.
