Sometimes when I need to animate a body part in a specific way, I like to use ghosting to see exactly where it goes. But when that body part stays within the silhouette of the character (or frequently crosses the path of other body parts, as in animating the legs and feet), the trails get jumbled up and becomes useless.
It'd be useful if there was some way to ghost a specific body part a distinct/different color. Or only ghost specific parts or while hiding others.
I'm thinking: ghost the selected bone's immediate child slots a different color? Or make the selected bone's ghosting overlap?
... or toggling visibility of a whole bone and all descendants in the Editor could just be made easier?
