title: OS X New Notifications
body: <p>Is there a way to check if there are new Notifications in the Notification Center?
  I mean, messages not seen by the user.</p>
  
  <p>I don't want to read the content, but only if there are fresh notification in it.</p>
  
  <p>I checked support docs, but I guess due to the sandbox, apps have no access to the item count of new notes in the notifications center.</p>
