I want to be able to drag dead bodies around easier, also being able to drag them through doors.
It was stupid in Oblivion that you could stealth kill someone and then their buddy sees the dead body and doesn't react. I want them to go in alert mode if they see a dead body.
So being able to drag and hide bodies would be awesome sauce
Also if dead bodies get found they should be disposed of quicker. Seeing a dead NPC laying in the streets for weeks is stupid. Alternatively if you kill someone in the middle of nowhere the body should stay there for a long time and maybe even decompose or something.
