There was a couple of house mods for New Vegas that had these sorting boxes you could use to sort all your stuff into other, more appropriate containers or place items automatically on shelves.
This would be nice to have in Skyrim for general items like potions, foods, ingredients, and books (though they do already have bookshelves that display items by using a container). Just simply put everything you want to store into one container, hit a button somewhere near it and all those items will be sorted into containers or on shelves, depending on the type of item and the container/shelf options of the house.
Maybe even change the houses a bit to make them better; like putting an apothecary satchel on all the alchemy tables that do not have one, or do something with that empty room in the basemant of the house in Solitude (the one with all the crates against the wall and the straw on the floor).
