Signer cannot see who has sent the request

[ssebech]

Is your feature request related to a problem? Please describe.
Neither the email notification nor the signing dialog shows the information who has sent the document signing request. So it may be hard to decide whether to sign or not if you don't know for whom you are about to sign it.

Describe the solution you'd like
There should be the name and email address of the requesting user indicated in both the email notification and right in the beginning of the document signing dialog.
