The image you provided is not the dashboard.How to change the ticket listing is probably the most asked question on the forums.This thread has directions for most contemporary versions of osTicket. http://forum.osticket.com/d/discussion//a-better-ticket-listAlternatively there is the forthcoming "Custom Queues" feature here:https://github.com/osTicket/osTicket/pull/2577Personally I would just wait for the Custom Queues feature due out in 1.11, or use the feature from github in it's current alpha state.
