Swap/Mirror Expression

jmucchiello

I have several tools that can swap/mirror poses (bones) left/right and do other similar operations on poses. Is there something similar for expressions?

I have v3digitimes Pose Mixer Pro. But that seems to only affect rigged stuff. Not expression parameters. 

I'm guessing it's not detailed enough to know what expression parameters have left and right splits. Hope I'm wrong about that. :)

Symmetry, and I guess other commands that are not hard-coded to handle only certain things, use the prefixes left/right, l/r and so on - but Symmetry itself is limited to  transforms, not any Modifier/Pose control (which is what you want).
