My addition:
Dear Bethesda, could you add a bookshelf/closet that automaticaly shows your books in order when you add them?
Even better: Make a system that lets you place the books (and other stuff) without everything flipping around, falling down etc. Interior decorating was impossible in Oblivion, because of the messy physics. In MW it was much easier, so there should be found a way you have physics, but can still control objects and put them exactly where you want them to be and aligned as you want them.
