Keep track of declined documents with the comments visible.
When a document is declined, the reason why it was declined is only available in one e-mail.
It should be available on the document as well as in the web interface. I could put a comment on the document (why I wanted to reject it), and in the Reject field, but only the reason in the reject field was kept and only available in the e-mail that was received. After that, in Box SIgn, you see that the document was declined, but you d'ont know why. That is a huge limitation.
