It would be handy for us from time to time to be able to send an email with an attachment (the invoice) from the bulk action section at the bottom of the screen when you have a list of orders on the screen.
For context we have some clients who supply their own label for shipping, so all we do is mark the order as dispatched and email a canned response advising to provide the label.
This would save us having to open the invoice just to send the email.
