When I am in "Open tickets" then "Search" should be related only to "Opened tickets" not to all.the same to other groups ie. "Closed ticket" "My tickets" ....
I like that idea - maybe an little (multi-select) dropdown-list next to the search field (or at the advanced search popu-up window) to specify the queue(s) to search in would be great.
I think here:http://forum.osticket.com/d/discussion//browsing-tickets-tickets-group-all#latestis a solution which show you all - I mean in the same way like this is now.
