So this guide https://docs.unity3d.com/Manual/BlenderAndRigify.html says to delete the WGT bones.
I'm guessing these are bones that were used to create the control polys for the rig... so why are these left laying around overcrowding my view tree instead of being deleted when the rig is done being generated?
Is there a way to easily remove the (100 some odd?) WGT bones all at once?
