Putting a slide in the hardscaping of your home shows an absolute dedication to having your small fry integrated 100% in your home. Or that you are still a kid at heart :) Either way, I totally want a house with a slide.
shelves attached to the inside of a closet door... Shoes....purses.... good idea. Add to the office or linen closet in a way that would store wrapping paper and supplies? Now THAT would be cool. I would use it for purses!
