Edit order is something we've all been waiting for. The only challenge is billing a customer for more than their credit card has been authorized but I understand why that is that way. Shopify did a great job creating this app as a result of listening to their customers.
This is a great app, but really should be a built in shopify function.
The app is 5 star in function, but the price is far too high. Would prefer a per use charge.
