Fairly sure the name says a lot. A Method of rotating Puppet-Job CNPCs would be incredibly useful; seriously, we literally can't have a character laying on their side at the moment, and there are a LOT of extra possibilities just by adding one little slider that rotates the puppet on the Z-Axis. Corpses, rough sleepers, sideways crawling, and that's just with a fixed sideways angle. with a free-rotate axis, we could have handstands, epic scateboard grinds, a knockout boxing punch, or hell, maybe even just trying to get to one of those really low cabinets that you store your mixing bowls in.
