The email notification is useless as a tool. Having to open the hub, go to the store, go to the orders, then click approve–and then click approve again every time I want to approve order is really not user friendly at all.
It would be great if the order notification email included a “approve this order” link that would go directly to approve the order, and a “cancel this order” link that would go directly to cancel the order to bypass the five other steps required right now.
