I'd like to see a mod for decapitation. I'm currently playing a two handed Orc warrior and it'd be cool if I could cut off limbs relative to where my final blow was on them. I'd like a mod that shows the second wielded weapon when you're duel wielding too, at the moment it only shows one, maybe combined with the ability to show both a bow and arrow on your back, not just the arrows.
Also, and maybe more importantly so; passive fucking horses. There's no point even buying a horse, if I get off in a fight it decides to join in, usually getting slaughtered by whatever it is. That retarded quest reward horse (called Frost, I think) decided to run off and solo a dragon that conveniently landed in the middle of a Forsworn encampment. It got butchered and it's body landed in a river, getting carried off a waterfall by the current. Retarded horses.
