I really thought that the Bone Hand feature would be useful but after some months using it, I find I have returned to Sprite hands for most situations. Why? Well, the most common application of needing fine control over the fingers is when your character is holding something, or perhaps playing an instrument etc. I was expecting that I could attach the relevant accessory in composer mode and then in stage mode bring up the layer manager and tweak the order of the layers for the palm, thumb and fingers. But shock horror - it appears they are all on the same layer, so no-can-do! What a shame. Come on guys, finish the job and give bone hand digits separate layers.
