In 14.0.1, the only user that can see the built-in notifications is admin. Other full administrators cannot see these. Furthermore, if an admin (that isn't the built-in admin account) adds a notification, the other admins can't see it.
This makes disabling certain email notifications (such as "Informational: Computer list changed") difficult as this is not intuitive at all.
My request is that all admins can see everything under Monitors > Notifications Notification conditions.
