Oups - I just remembered my biggest dream feature not yet added, I'd like a way to have multiple lot categories per lot. Assigning a section of the build (room(s) or a full floor even, if that is the only way) to additional lot category. This would make it possible to run a decent mall or simply adding a functional café or small bakery to a vet clinic or a small flower shop at the corner of the Lounge. And while at it - why not assigning such a business section to your residential lot? Back in TS2 we could live upstairs and run a shop on ground floor. It opens a ton of possibilities.
