I think this would be nice to have. Or is there already a way to view this information? For example I have a boat to catch in 3 hours but I can't leave without receiving payment. Maybe this feature will be added in an update?
There are currently no plans to put a payment queue as we have higher priorities to speed up the entire middleman process that are already for the most part completed but need to be implemented. The reason being that payments are typically processed between 1-72 hours. Just need to wait within that timeframe.
