We have customer notifications turned on for "Public comment added" but turned off for "Public comment edited." When an internal comment is changed to a public comment, this is treated as a "public comment edited" but I think it should really be considered a "public comment added" situation. 

The problem this creates is, if an agent accidentally adds an internal comment when intending to add a public comment, correcting their mistake (simply changing it from internal to public) doesn't send the notification as expected. 

We turn off public comment edited because we don't want a notification re-sent if they correct a spelling mistake in the record.
