Previously a list of expenses could have two states: open or closed. Now it has three states: open, to paid, paid. When a list is closed, it becomes "to pay" until all the induced debts are mark as paid. Once a list is "paid", it can become "to pay" if one the debts induced by this list (or one debt simplifying the debts induced by this list) is marked as "not paid". And it becomes "open" again if you re-open the list.
Kidanki exists in two versions: the "anonymous" version where one can create and share an expenses sheet without signing in; the "connected" version where one signs in and can manage several expenses sheets and several groups of people. Today, version 3 for anonymous has been released! It works on mobile, tablet and desktop screens, it's fast and it couldn't be any simpler.
