It was a pain in the butt to place them where you wanted, so I hope the physics in Skyrim will make this easier.
Oh sooo true, unless they were flat, they would either fall or roll around then flop down, also it bugged the crap out of me whenever it would say "not enough room to drop this item". or however it was worded, when i would be standing a yard+ away from a wall or anything..agh.
Rant aside i agree with you, i would placing things in your house will be improved, but not limited by any means.
