Y'know it's actually really funny, because when I say 'fixing them up' I don't really mean playing interior designer too much. Like in Oblivion I would have use a certain container for books, a certain one for random cool gear I'd never use again but want to hoard like a packrat, a collection of ALL THE KEYS TO EVERYONE'S HOUSE because I was silly like that, etc.
Other than that I'd do what I did in Fallout 3: buy all the stuff and be all "oh cool look at all this stuff" *looks a while*....okay, time to go adventure"
I think it's sort of the thought of it all that does it for me? I'm not sure.
Being able to move stuff around *is* neat, just...not something I digged into very much.
