Adding either privates or public notes to a ticket is very easy. This add-on allows users to attach public notes to a ticket and staff members and admin to attach public and private notes.
Private Notes are seeing only by Staff Members and the Admin, the client can’t see this type of notes. However, Public Notes are visible by Clients, Staff Members and Admin.
The client can create only public notes.
The admin can see the notes through the WordPress Admin Dashboard when editing a ticket.
