The new portrait image system (that'll be in the next major update) is probably the feature I'm most proud of!
I'm currently working on home customisation, and that's shaping up nicely. Homes for sale or rent are procedurally generated with various numbers of rooms, floors and even buildings. You can then customise these by renaming rooms/buildings and outfitting them as you desire. Many upgrades add new action buttons when you're in that particular room. For example, the 'Watch TV' action that's currently in the game is now connected to a TV home upgrade
