When sending to multiple signers, it would be nice to have an option where you can hide the email address from other signers. For example, sometimes I have to send to a personal email address, but I don't want the other signers to see that email address. Also, I am unsure if the signers also get a copy of the Audit Report (that is usually attached to the document for the sender). I hope they don't get the audit report, because that report lists all the email addresses it was sent to.
