In Oblivion you could pick up and move around small items such as food,weaponry,utensils...etc. You could also move the limbs around on a dead NPC but you could not pick up an enire dead body (Atleast on console versions) I would like this to be added into Skyrim so that I can move/dispose of dead NPC's lying in the streets.
I think it would also be great to have a positioning tool that would allow you to rotate the item you have picked up so you can use it to place objects/decorate your house in Skyrim the way YOU want.

I prefer use other mods then this
Some of mods allow to take body into inventory or decompose it dismember by parts, I use them for my evil characters.
For my good characters body can be buried in ritual
