Another one for the physical goods crowd.  When a client marks an order as approved, it automatically gets marked as completed.  Which is fine for digital art (probably), but it buries the listing behind all the ones that came after it, making it difficult to find it again to give the client their tracking info, etc.  

It would be very helpful to have a manual switch for the artist to mark the order as closed, so it can remain on the front page, or on a separate list for completed-but-not-closed orders until the item has been received by the buyer.
