Partially solved. In ticket-view.inc.php, I was able to add hyperlink next to the ticket number at top (see code below). However, open into new tab not working (target blank). Any ideas on how to fix?<div class="flush-left"> <h2><a href="tickets.php?id=<?php echo $ticket->getId(); ?>" title="<?php echo __('Reload'); ?>"><i class="icon-refresh"></i> <?php echo sprintf(__('Ticket #%s'), $ticket->getNumber()); ?></a> / <?php $ticketAdmin = ltrim($ticket->getNumber(), '0'); ?> <a href="../sample/sample.php?ticket=<?php echo $ticketAdmin; ?>" target="_blank">Admin</a> </h2> </div>
