Slot inventory (Diablo 2) is not so bothersome if developers don't make U or Y shaped items...
Combining inventory space and mass encumbrance, but keeping it simple with item shapes, would be awesome because realism is important in TES (at least to me) and seriously: how many full leather armors can one carry in backpack???
They could also mace a Auto Fit option so the game can fit items in inventory automatically, so the only things this slots do are limit you in carrying ton of big items. Along with this slot inventory screen there should also be a plane list of items with different categories.
Papers and money should maybe take up 0 slots.
It would maybe make introduction to shrink object spells
