Great add-on but just spotted that the automatic date/time stamp is updated when additional info is subsequently thus irretrievably losing the date of the original note.
This is not good. The original date MUST remain.
In the unlikely event that the user wants to effectively REPLACE the original note, they could delete the original one and then add a new one. For UPDATES, the user can add their own date within the text if they wish. In any case, being unable to UNDO this automatic date change is a real no-no.
