The interface is very easy to use with all information at your fingertips - no scrolling or clicking required! It's also great that I am able see my shipments as they are being calculated so it gives me peace knowing where everything stands between origin/destination ports & airports until final delivery has been confirmed by customer (or if any issues arise). There isn't much else about this product which could be improved because its an excellent tool already; but perhaps some sorta widget system would allow us greater visibility into our inventory levels while we're processing orders without having multiple windows open?
