I'm no modder, but I'm pretty sure this would require the construction set that isn't released yet. However, I figured I'd suggest it anyway. I really want some way to create sets of armor or clothing. Example, Say I am running around fighting bandits. I want to have my best fighting gear on, so heavy armor with enchantments supporting one-handed and block or something. Then I get to a part where I want to sneak past some guard. So I switch to a set of Nightingale Armor with a ring that increases my sneaking. I'm suggesting that a mod be made that adds another option to your 'items' menu called "Sets". Inside that section you have your list of created sets along with 'Create New Set'. So, I can choose 'Create New Set', then name is 'Sneaky' and choose the equipment used in that set. Then I can favorite that set so that while I'm running around, if I need to sneak I can simply open my favorite and choose 'Sneaky'. :D
