I'm quite the archer enthusiast in Skyrim but I never felt that the quiver position was to my liking. In real life, I have always preferred to have my quiver at my side, fastened to my belt.
I think it could work quite well for people who has one-handed swords on the back. So this is my first official mod request. I'm also interested to know if anybody else is interested in this.
Also: I'm fully aware of "Chesko's Belt-Fastened Quivers". Though a great mod its positioning of the quiver at the lower back was never to my liking
