Oh oner thing i'd like ... knees and elnows! The problem is it's useful for armour for adding armoured bits to cover those pieces. and of course knee and lebo pads for sports scenes i guess .. but for most clothing it might be a hinderance. It might work if the group was kept really really small though. Unfortunately with poser's rigging if you put any kind of armour over knees and elbows you get really limited. You have two options for doing it and both are bad. a conforming figure would bend in ways that will crush armour that normally wouldn't bend but rather be hinged on rivits. So if you have a really nice knee guard with a clover leaf shaped side wing.. when the leg bends you have compacted mush. If you go the smart prop route you either have to parent to the thigh/shin or for the arms, shldr/forearm. This causes thos smart props to fold out with one group and ignore the other so the bending looks bad. since most folks won't care for the added groups i'll just hush up now.
