Yes! This is a main issue for me and the reason why I joined this forum. Before I completed the CC l imagined that every room would have a use. I consider the CC a main objective for the game, so in completing it, I think it's not too much if we can:
Pantry: cook, with the fridge filled with some random ingredients/pantry staples
Craft room: sew, and make a pixelated painting
Vaults:make deposits and get interest, like a bank
Boiler room: unlimited coal, with a furnace
Maybe somehow play music in the main/central room.
More events there is also an awesome idea, but I only ask for more people to gather in the same room at regular intervals daily, and just speech bubbles would make things feel more alive (quote: a real sense of community.)
