Just to clarify since I haven’t understood what you meant either: do you mean making it so that when you stop using free-look you want your gun (and the rest of your body) to move/face where your free-look camera was pointed, rather than where you were originally facing?
I think I’d be against that, or would even just prefer it to be an option in a settings menu instead. Doesn’t really seem like a quality-of-life addition, since I personally would rather snap back to my previous camera angle than to move my body towards the free-look camera angle’s position.
