I've heard different opinions about current UX of the script and some people are claiming that breaking slider limitations program-wide (not only for flexes) is a negative culprit when choosing to use that script or not.

So I'm thinking about adding second option (additional script for the rig submenu) that will create a control group with new sliders connected to the flex values which you'll be able to remap. You'll need to apply this script to every animation set once in a shot/session.

Please share your thoughts here.
