I did a bit of searching and nothing came about...I'm wondering if there is a such mod that makes the player track nearby NPCs and enemies by turning their head. Oblivion had this but it seems absent from Skyrim. Anyone know of such a mod?

As far as I'm aware nobody has done anything about this yet. But it is something a lot of people have wanted, as you can see from a few of these threads:
