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.
Once you have an estimated date for the prediction to happen, you can plan it. This will change the status of your prediction to Planned and you'll no longer find it in Unplanned, but in All.
