Better UI - navigating through the sims menus for interaction is terrible, specially when you have all the packs. Also, a better BnB catalog, same reason, when one does have too much stuff gets terrible.
Better Whims/Wants & Fears TS2 style - It's nice that we can have full control of a sim, but after a more then 1k hours of game time (which is not that much considering the game is like.. 8 years old? +/-?) it gets some what stale. In sims 2, although it suffers from staleness/same-same-y too, sims had more agency on their lives. Like how whims work already, it could be a toggle-able option, because sometimes you want that, and sometimes you just want to make sure the Grimm Reaper is busy control everything.
Life stage reworks - Teens and adults feel the same (and I'm not even talking about the height thing). Young Adults and Adults are almost identical.
Better Townie's Outfits - Come on, game, you have the whole "stylized looks" thing on CaS, at least limit random townies to pick clothes from there so they don't show up with random clothes that make no sense.
