Can be done with a script. What you won't see, however, is actually clicking the joints, and pretty graphics. Because handling clicking is not in Lua already, I believe.

Even so. Not exactly to the topic, as this is about what features you'd like to see Lua have, not scripts.

PS. Wiki would be nice. If hampa could just upload it, I could make the necessary starter pages.

I've been wanting something like this for a while:

A mode that disables frames and movements. One that instead of making the fighters have physics, just make them like action figures. You can move them at all the joints. This would allow you to make amazing poses that you couldn't normally do. You would also be able to dismember things and pose them as well.
