When viewing the document summary, you will see a section on the top of the page containing all of your document details. It displays the status of the document, the name of the doc, the company it was sent to (if applicable), the value (if a sales doc), the expiration date, and when the email was sent.
You can update the value and expiration date by clicking on them. To view the email you sent out, click on the email icon with the date. You can also access the main document menu (grey box with three lines) from this section, which gives you a list of actions you can make to the doc.
