This mod implements headtracking for the player. Your character will face other actors similar to the NPC's in the game. Your character will first prioritize actors who are currently in dialogue with you, then actors who are currently talking to any other NPC, then actors who are straightest in front of your character. When moving, the distance at which your character headtracks actors is shorter than when standing still or sitting.
