Maybe instead of the often long and confusing hierarchy menu, it could be a separate tab or docker? That way we could open it to work on a scene and tuck it out of the way like the library or other panes when not in use. Aside from the hair and cloth rooms which give me nightmares trying to use them, that's among my biggest Poser peeves. We really need a scene/hierarchy docker.

Oh, and since we have face and hand cameras, how about feet cameras? Nothing worse than slaving for ages on the perfect scene, then after it renders (maybe an hour or so later) you discover your character's feet aren't where they ought to be and those heels are all messed up.
