Most of mine have been mentioned in one form or another but I'll throw them in for my two cents worth anyway:
More activities and quality of life stuff for elders. I hate that they eat, sleep, die.
Spiral Staircases!
Witches
Burglars and firemen
Trash Compactors
More Selvadorada style vacation spots (I mean, vacation spots with actual things to do. OR was terrible because you could do everything there was to do there, anyplace else and be less bored.)
Imaginary Friends. I know they are controversial because as many people find them creepy as people who love them. I loved them and their dumb little walks :)
Private Investigator job- I'd just love to do it. I think it'd be fun.
