What small update would make a big difference for you?

The ability to assign npcs to certain roles and specific worlds. I have a lot of npc interactions that damage my played sims relationships
Flirting
Cheating
Mischief
Negative reputation from negative npc encounters
If they could just work stalls, bars etc and not interrupt dates and pick fights that would be great. Be very very background characters that I could choose and assign.

Keep Del Sol in Del Sol. I hate the incite cheers and my Sim is compelled to watch.. at salty paws in brindelton.

My biggest issue is npc being to much in the foreground and would prefer them to be less...disruptive.
