ShipStation needs to have a functionality to track the incidences of shipping mistakes per user. If a customer calls back and says they are missing something, or something was wrong with their shipment, I would like to be able to record these notes on the shipment and tie it to the user that verified the shipment.
I think adding a column to the shipments grid with the title "Shipping Errors" with a text field that allows for shipping managers to record issues would be feasible.
If Shipment 1000110 was missing one T-shirt and was verified by John, a manager should be able to record these notes on that shipment to use as a performance indicator.
