Edit documents if they haven't been signed yet
Often I will send off a document to be signed and it will need to be slightly corrected in some way and resent. If no one has signed it yet, I should be able to edit it and resend it for signatures. Instead, right now, I have to create a new document, make the change and then send it out for signatures again. This clutters up the documents because you also aren't able to cancel/delete a document that has been sent for signatures, even if it hasn't been signed.
