If this were to be implemented. It would not be possible to edit the notes in the mobile client, only add new notes. This is because it is one long text, and it is not easy to determine if someting is a timestamp, if someone edits a note, or adds or both, and what to do then.
worker can only add new notes. They should not edit previous notes. It is to ensure the information and that no other workers change the text.
