Just as a heads up: I'm planning to rework joints other than the knees, as well. Definitely the hands (including fingers), elbows and feet, possibly the shoulders and neck if I can manage something that improves on the current rigging. All as individual add-ons, of course. Some of those might break existing poses and conformers for Antonia 1.3. So maybe the best way to look at them is as previews of some future version. I'm pretty sure this will, even with the most detailed and explicit warnings and explanations, confuse some people, whether you also make JCMs for the unmodified 1.3 or not. Antonia has always been and will always be confusing, lol.
