One thing i do a lot is copying the behaviors from one rig to another.
So i have to open the rig, select layer, copy behavior, open new rig, select layer and paste behavior every time i need to reutilize something.

What if we stored these behaviors as presets?

We could also have a way to point to them in photoshop, like naming a layer to something like:
Layer 01 [preset: "Cycle One way + Pause"]
