I would like to definitely see the weapon racks and plaques and cases fixed along with the mannequins...
And it's definitely quite annoying that after I spent about 2 hours decorating my house the way I want it that I leave and come back an hour later to find there's been some massive party that I wasn't a part of and everything's on the ground... At one point I killed my housecarl and wife in solitude to fix the problem but apparently it's actually the ghosts from The Exorcist doing it and not the people constantly walking around the house...
Also I'd like the Civil War questline fixed so that my main character can continue the game...
