Here is a code diff for that file that works with 1.9.x .... I hope this is useful to some! I didn't want to see the priority. So I commented that out, but you can easily un-comment it if you want to see the priority. I also didn't mess with getting it to display the up and down arrows because it looks like I'd have to modify a different source file, and I wanted to keep it down to one file mod.- MikeThis is a diff, which you can use with patch if you wish, or you can manually apply the changes too. In case osTicket got modified from when I made the patch, that is.. (by hand is safer and it's not large.)---------------------------osticket:/var/www# diff -u tickets.inc.php.orig tickets.inc.php--- tickets.inc.php.orig 2015-10-14 15.188621700 -0400+++ tickets.inc.php 2015-10-14 15.672621700 -0400@@ -166,7 +166,7 @@ $sortOptions=array('date'=>'effective_date','ID'=>'ticket.`number`*1', 'pri'=>'pri.priority_urgency','name'=>'user.name','subj'=>'cdata.subject', 'status'=>'status.name','assignee'=>'assigned','staff'=>'staff',- 'dept'=>'dept.dept_name');+ 'dept'=>'dept.dept_name','duedate'=>'duedate'); $orderWays=array('DESC'=>'DESC','ASC'=>'ASC'); @@ -217,7 +217,8 @@ $qselect ='SELECT ticket.ticket_id,tlock.lock_id,ticket.`number`,ticket.dept_id,ticket.staff_id,ticket.team_id ' .' ,user.name' .' ,email.address as email, dept.dept_name, status.state '- .' ,status.name as status,ticket.source,ticket.isoverdue,ticket.isanswered,ticket.created ';+ .' ,status.name as status,ticket.source,ticket.isoverdue,ticket.isanswered,ticket.created '+ .' ,ticket.duedate'; $qfrom=' FROM '.TICKET_TABLE.' ticket '.
