I doubt there will be many who agree with me on this one, but one of my major gripes about Skyrim was the simplification of the players ability to manipulate objects in the game. Prior to Skyrim, items could be grabbed from any side, lifted, turned and positioned as the player liked. The player could easily decorate his house with things he found adventuring, and once placed they stayed where they were put. Even corpses could be grabbed by the limbs and posed for comic amusemant.
In Skyrim it seemed like each item only had one grab point. You would pick it up and it would flop around uncontrollably. Trying to do something simple like righting a cup that had been knocked over was a nightmare. When you finally did get it placed and left the area, it would be on the floor when you got back.
I really, really hope they restored the world manipulation functionality to the level it was in earlier games.
