I would like to see an option where the Z position (depth) can be adjusted within a rigged character, such as on a bone or sprite. For example, if I'm creating a character with a hand-held object (e.g. weapon), I'd like to be able to place that object in front of the torso but behind the hand on the Stage. This feature currently exists, but at least to my knowledge, it doesn't apply to individual pieces of a rigged character. I think this would open up 2D animation possibilities considerably, allowing for increased prop production and such.
