Item storage when you are levelling crafters would be nice. The retainers space plus your own just never seems enough. I wouldn't mind a chest built only for crafting items that you can stick in your home. Or a dye chest that you can only stick dyes in. A weapons rack that you can only place the weapons you want to keep on. That sort of thing. It would increase storage but also add furniture, make the homes feel more useful. I dunno, just thinking out loud.
