The In-Process orders screen is very similar to Pending Orders. You have the same search fields, the same information displayed on the screen and the same batch actions (with the exception of move to in process, instead you can move back to pending). Also, by default the In Process screen sorts by and displays the shipping information. This allows you to quickly jump to the Order Shipping screen where you can fill the order and email the tracking information to the customer. You can use the sort to reorganize the page and display other information as with Pending orders.
