I understand ofc. We are already using it in our live store, but ofc other testers are needed.
You mean in AdminLogs or something new? If it would be new, I believe we would better make a order history concept, that shows everything (like order status change, emails sent, customer messages, customer service cases) in a nice history tree or so.
Have you briefly looked at the concept. How do you think about this:
"Technically a new cart is created based on the order values. The cart is used then to recalculate the shipping cost."
