Works great, I like that it doesn't actually modify anything on the armature, and you can revert the changes at any point. "Con size" could perhaps be based on the update callback, so you don't have to press a button to do it.
That’s a great suggestion. However, adding a real-time update callback for bone size would add quite a bit of complexity to the codebase. If you're up for it, feel free to fork the repo and submit a PR!v😜
Good
yes! this should be default.
