Exactly what I was looking for

Before this I was manually updating tracking numbers in customer note, and they were starting to get annoyed that they were receiving two emails (one customer note, one order completed) and they had to track their orders manually.

This plugin has all that I was looking for, and more. I just wanted something that could add the courier and tracking number into the completed order email, but it has the additional bonus of being able to track a pre-input tracking number from the “My Account” page. Thank you!
