Precise movement, block by block doesn't really fit for Skyrim..
I agree but a lot of games have got similar things wrong. I would prefer item placement in houses as in an old MMO called neocron which is basically just placing it where you want by equipping it and rotating it from there, but that is kind of irrelevant because no one here will have heard of it. As for pushing blocks in dungeons I would only like it if you could do it in first person without going into a long winded animation because that would subtract from the style of the game in my opinion.
