Hello Val,

I have some specific question:

1. Is there way how to write down movement of an elbow? Maybe it is possible to use some "neutral" arrows for that somehow.
2. As you know, in Puddle there are two rub symbols. One "left" and one "right". Is there any difference in the direction of movements?
3. I am not sure about using (( alternating lines. I don't see any way where this can be useful, due all information are included in movement arrows.
4. Is there easy way how to write down circular+forward movement?
