URL in order confirmation that links to the order
Like almost all other cart, when you get an email notifying you of a new order, this email contains a URL that can quickly open the order itself. This negates the need to open browsers, find the site, find the back-end and find the order. A simple "View Order" link on the confirmation email sent to the owner of the shop will simplify the process.
Here is a quick tutorial I wrote for you to add this link: http://www.vanbodevelops.com/tutorials/add-a-link-back-to-the-order-in-woocommerce-new-order-notifications-email
