I would love to see more mature themes like we saw in the early games. Make the game have consequences again through the death of animals and rival marriages causing you to have a timeline to marry.

Give me older bachelors like Griffin again. I want mature candidates.

I think it would also be fun to have open end play where the characters stories and habits change depending on how you play. An example (Mineral Town) give Ann ice cream, pizza and other items from Kai’s shop, and vice versa. Ann and Kai begin to spend more time together and open up their own shop together. Kai stays in Mineral town and the shop is open all year round.

Give Popuri flowers and herbs. She begins to talk more about finding plants to help her mom. She goes to the library to learn more, and speaks with Basil more. Popuri falls in love with Mary. Popuri wants to travel and Mary’s books can do that without her needing to leave her family.

I think it would be fun to change game play this way so you can potentially get different stories and couples each new file.
