Check em out in your house! You can now set a selling price for the items in your SDB, and other people can buy from you. The SDBs will hold your currants for you, and you can collect it any time you wish.
If your reaction is "Well great, but only people who can enter my house can buy from me?!? What's up with that? Think, Tiny Speck! Think!" then we have another release coming in the next week or two that will put all your concerns to rest, and which may make you unnaturally excited.
(This functionality required us to change the click interactions on SDBs; whereas once they had a single click action to remove an item, they now always bring up a menu.)
