The Order Details View shows all details which are relevant to the store owner. You have three tabs in the upper part: Order Status Change, Order History and Modify Order.

In this part of the order details screen you see the list of all purchased products. If the products are downloadable products, you can re-send the Download Notification Email or re-initiate the downloads if the maximum download number has been reached or the download period has expired.

You can also change the order status for single order items using the status drop-down list in each row of the order item list.
