[Bf-committers] Armature Symmetrize & Bone Roll / custom shape

I have some questions/remarks about Armature Symmetrize [0] & custom shapes

Based on very simple Armature [1] :
I used Armature Symmetrize to generate half part of this rig.
But I think there is a problem with bone roll. Now, for forearm bend, I
have to use negative Z rotation on L part of the rig, and positive Z
rotation on R part, that is not really good for animators.
I think we maybe have to change how symmetrize tool works to take this into

Another suggestion about custom shape :  After recent commit [2], I thought
that maybe another option can be added to use "roll rotation or symmetry"
option to display shape. As use can see on blend file [1], on shoulder, if
I really want to use these roll bone (that was discussed on 1rst part of
the mail), I have to duplicate custom shapes in order to make a shape
symmetrical to another.
Same way that now we can use scale option, it can be useful to use only 1
custom shape with option to set rotation or symmetrical.

What do you think ?
