There are situations when you know you have to pay a debt to someone, but you don't know when. Or you have an invoice for a client you haven't heard from in a while.
Save these predictions in ThinkOut even though you don't have an estimated date. Just to keep track of them.
How to do this?
Go to Predictions -> Unplanned and click on Add unplanned prediction. Fill in the necessary information in the form and hit Add.
