Maybe a mod that makes the weps that could lay down (Ex. L4D) instead of seeing them floating.
I think it'd be great to have some sort of "setItemSpawnRotation X Y Z" event or wrench menu preference would be awesome. By rotation I mean, rotate the weapon's position so you can have it however you want. Not spinning.
I also think being able to spawn items upside-down would be nice too, like for swords and spears where you want the blade in the ground.
