Fast Tools-Biped Replacer

Have you ever needed to update your (Biped) character after a whole animation is done? even needed to replace it while keeping your animations as intact as possible ?
Tired of tedious hand labor replacing sequences with updated version of rig (Biped)?
well , you may need watch this demo of my tiny tool that needs only to let it know which will replace which only ONCE and it will remember that for ever as you dont change parameters for another characters
Have fun
