Hello,I am using V1.10 and in Agent screen, under Tickets -> Print Icon on the top right, I would like to add a third line 'Print Invoice' linking to my custom php file for invoice... tickets_report.php?id=<ticket_id>&a=print and send the output to PDF, or open the php in a new page.Can some one guide me which file to modify for that sub-menu? If you could even help me with the code, that would be much appreciated.
