Add the ability to export estimates as a downloadable pdf. Currently there is no option and when viewing the document online, there's a banner that shows "Estimate is in draft mode, please check back later."

When using a 3rd party salesman, using the send functionality isn't an ideal method as it asks to accept or reject the esitmate. It would be better in some cases for the salesman to have a pdf version to present to the end customer in person or via email.
