I tried the morphing Demo Rigs.
In the Rig Settings I find a window (5 of 6) with the parameter values but not the morphed Parameter. Just a text for example "10 morphed parameter(s) " or " 17 morphed parameter(s)"
Is it possible to find the parameter which will be morphed or will this be indicated maybe in a final Version 4.x.
Perhabs a topic for "request" but up to now I did not try everything.
Anyway it will be important to document everything when you use this function otherwise it will be confusing.
