Hi John,
Yeah I don’t think we have anything on cloth simulation for animated characters.
I’m not an expert in that field as all the all the animation and rigging I deal with doesn’t use sim for the clothes. They are just skinned to the armature.
I do know that Blender Pirate (Jeannot Landry) is working on a course at the moment that covers Hair and Cloth.

But I don’t know when this will be released.
As for the “Clothes in Motion” add-on. I haven’t used it, it does look pretty handy although all the examples feel like the cloth is moving too much for the material it is meant to be made from – if you know what I mean. But maybe there’s a easy way to edit that in the add-on.
Sorry if this is another answer you weren’t hoping for 🙁
