The two biggest things I want are the option to disable memories, and the switching of different makeup for different outfit categories. Memories take so much room in the game (no pun intended), and I think EA should give us the option to enable or disable memories themselves.
Makeup: I like to do different makeup in real life, so why can't I do it with my Sims? It's no different than picking a hairstyle, with your outfit category, really. So I think it should be done, like say, light springy makeup for everyday, red lipstick for formal, no makeup for athletic, swimming or sleep.
