I really enjoy the variety that the armor dye system has brought to the game, but I find that everyone owning the identical version of a scant few mounts (though it has gotten better) to be lacking.
Why not create a feature where the saddle can be crafted, depending on the quality of your Medium Armor skill, and subsequently dyed, to remove the sameness of the mounts? I envision that all racial styles should be represented. I know this is a lot of artistic work, but would be way better than just adding horse armor. Though, for Blacksmithing aficionados, that would be great too. As long as it's customizable by race style and dyeing.
Also, can we please have horse-riding in first-person?
