How can we improve WHMCS?

Occasionally we need to share a customer email with that customer or a third party to prove that we sent a specific email.

It would be great to be able to actually print the entire email, using the browser's print function, after clicking on one under the customer's 'Emails' section. A good example would be the 'View Printable Version' feature for Support Tickets.

Currently, if you try to print a customer email using the browser's print function, only the visible portion of the email is printed along with everything else that happens to be on that page.
