Add OUTSTANDING balance in the fields, for the Shipping tab

The benefit of the SHIPPING tab is that you don't need to go into the order directly to mark it as shipped.

However, it does not show you if there is a balance pending for each order. The only way for me to know if the multiple orders that I am handing over to the customer have a balance pending, is by clicking each order# individually, and check if each one is paid.

It may not seem like a hassle, but if I am handing over multiple orders at once during rush hour, it would be more efficient to see which ones have balance that requires my attention and which ones I can dispatch with ease.
