One more thing…<g>
I was just thinking how selection sets in the keyframer, combined with the
ability to animate individual vertices would really help character
animation.
For example imagine a persons arm, you could select and link the vertices
on the forearm to a dummy object and select and link the vertices on the
upperarm to a different object.
That way you could rotate the dummy objects, and have the vertices pulled
along while keeping their original shape.
