So, this being early access and a lot of things obviously still needing to be implemented, I still figured I should add my two cents.
A possible suggestion is to maybe include such things as basic household goods like pottery and furniture which could be made in existing buildings like the kiln or carpenter.
These maybe provide a bonus to productivity or happiness and possibly appear in houses that have them in their inventory.
This could also be extended to outright luxuries such as spices, honey, or other non-necessities. Or at least would provide a framework for future modders to implement them if they so desired.
