Consider head as a part of the body

Maybe the default structure where head and body are read by Ch as different layer groups could be better if the head was read as a sub-group of layer inside the body layer group. That way you could easily solve the common head floating issue by simply tagging neck on the layer group itself just like shoulders, hips and waist. Hieararchy idea:
