PM subjects in PM Tracking page is not hyperlinked and its a problem if you forget the content and want to check back.
So, here is a little jQuery magic to make all the PM titles clickable which will take you to the original PM in Sent Items folder.

Open template private_tracking and find the variable {$footer}. Add the following script just before that:

<script type="text/javascript">
  $(function(){
      $( "input[name*='readcheck']" ).each(function(){
          var link = rootpath + "/private.php?action=read&pmid=" + (parseInt($(this).attr('name').match(/\d+/)) + 1);
          $(this).parent('td').siblings('td:eq( 1 )').wrapInner('<a href=' + link + '>');
         
      });
  });
</script>

Save the template, BAM!

All of the PM subjects in tracking page is now clickable.
