I'd love it if someone could make a mod to stop the horse auto attacking, and make enemies ignore the horse once I've dismounted it, or at least make it run to a safe distance, or even just mark it essential. I am going to look into making such a mod myself but I don't have much experience with mods and have never modded a Bethesda game so probably won't have much luck. If anyone else knows how to do this it would be great.
