Improved Signatures

Signature request page reorganised

The signature request page is ordered by task: status and next step, signers and their fields, sending settings, then files and activity.

The signature request page now opens with the request's status and the next step, followed by its signers, how it is sent, and, once sent, its files and activity.

Each signer row shows one action at most. Moving, removing and changing a signer are in the row's More menu. An access code is set or cleared on the signer's row. Place fields sits with the signers, the expiry of a sent request is extended beside its current date, and file hashes are listed once below the files.
