It would be AMAZING if fillable PDF forms could have the option for more than one person, BUT NOT ALL, to edit a field. For example, I have a template that I pre-fill, then send to the owner of the company, who reviews it and signs it, then it goes to our customer for signature. First thought - I messed up on a date when I pre-filled it, so now I have to re-do the entire document, because Signer 1 (company owner) can't edit this field, and if ALL signers could edit it, the final signer, our customer, could conceivably make changes to the document after Signer 1 has completed everything. Scenario 2 - we have fillable fields that I sometimes have the information to fill in and sometimes I don't, so Signer 1 needs to fill in those fields. I would like to be able to fill in as much as possible, to minimize the time required for him, and only have him fill in fields that I have no reason to know. In all cases, we do not want the final recipient to be able to make changes to any of these fields.
