(I've installed gogo loco correctly and everything works as expected, so this post doesn't need an image.)
It makes some sense for gogo loco to disable poses & height adjustment in FBT, since you're able to make those poses IRL instead. However, with fullbody estimation becoming more common, or if you just want to sit a different way IRL, it would be great if those could still be used in FBT. Is there a way to force it to do this? I have experience with animation layers
