Hi @Devi1903,
Perhaps someone else will jump in with ideas. But, speaking for myself, this is beyond the scope of what I have time to think about.
Keep in mind, however, there there is nothing osTicket Awesome specific about your questions.
In other words, you could post the same questions in the osTicket / Modifications forum and at least 100x more users will see them.
Just remember to press SHIFT + O to display the ticket queue in vanilla osTicket before making screenshots. 😉
(Oops. On second thought, you would have to apply the same modifications to osta/old/include/staff/templates/queue-tickets.tmpl.php, but it might be worth the effort to do so).
