How do I change status from "Pending" to "Completed"? Ubercart is install without any payment gateway. The workflow is to take user orders via out website and payments are handled offline. Once we received payment and shipped the product, we'd like to mark the order as Completed.

Here is the doc:


  
  When a customer moves from the checkout form to the review order page, a new order is created with their information in the default
  status for the in_checkout state. (By default, this is "In checkout.")
  When a customer completes checkout, the order gets moved from the default in_checkout status to the default status for the post_checkout
  state. (By default, this is "Pending.")
  The rest happens manually by order administrators, but the other two default statuses are "Processing" and "Completed." Processing is
  actually just another status in the post_checkout state while
  Completed is the default status for the completed state.
  


However, I don't see a status dropdown list or similar UI element for changing an order's status when editing an existing order:

How can I change the status from Pending to Completed?
Under the drupal 7version of Ubercart 3, order status would be changed using the dropdown found under
