+1 to fixing the pause button, more ways to earn/buy lavastones and crafting magic and air.

Maybe adding more limited-time events like the Christmas lanternmaking one? And having them automatically be offered as an optional side task. Some way to use those useless lanterns and crafted items.

Ability to earn all exclusive outfits from Survival Mode. I want to make elves and vampires in my village!

Some way to customize our villages like Virtual Families 3 maybe?

There definitely needs to be more things to do after we finish the story. Our villages sit there doing nothing and the game's essentially abandonded.
