I'm not sure if this has been made already or not, but I haven't found anything on it after strenuous searching.
It would be awesome if there was a mod that made it so that the bow is hung around the player, rather than being glued to their back.
So, wearing it with the string slung across the chest. It would also be awesome to see the quivers be a bit lower and have straps around the player (same with two handed weapons), again, rather than being glued to their back.
Just a thought, it would make carrying gear look a bit more organic.
