I've moved this thread to mods and customizations.I'm not real sure what you are referring to as the "ticket overview". Do you mean the open/closed/my tickets queues? If so then at this time you cannot, or you need to mod the core files. This thread ought to assist you do the latter: http://forum.osticket.com/d/discussion//a-better-ticket-listIf you mean the ticket view page (when you click on a ticket) then you can't at this time. You would have to edit the core files to do so, and I do not have a link handy for how to do that.If you edit the core files you should be aware that changes you make will go away when you upgrade. And any problems that you encounter are yours. We will tell you to reinstall stock code during troubleshooting.Please help us to help you by reading and following the posting
