I made a simple door with a one-bone armature that allows it to swing plus/minus 90 degrees, and I wanted to have a widget to grab while posing it, instead of using the bone itself. Something like arrows pointing in the direction of each axis.
How would I assign such an object to the armature so that when in pose mode, I see and manipulate it instead of the bone?
I've seen UI in other rigs (Pitchipoy, etc.), but I can't tell how they're set up for this. There's a Custom Shape property in the bone panel, but it seems to replace the model for the bone itself, whereas I'm looking for a sort of proxy for that bone.
