Add something like the Coin Collection from Salem to HnH. These would be collectibles that spawn in natural containers (tree stumps, tidepools, squirrel cache, hidden hollow) and can be crafted into a curio. Bonus points for a Piggy Bank. Natural containers feel pointless atm. It would be cool if there were more reasons to interact with them.
When there were no bough baskets, the empty stumps were often used to store items in the beginning.
I don't know about the coins, but it's a good idea to find something other than a tree worm in the stumps. Without sliding down to the level of armor falling out of insects. Perhaps the leaves of trees, other insects, a curiosity.
