Add a close ticket button to individual ticket view

When working on several tickets, the current ticket I am working on can get lost in the tabs of opened tickets. Often times the current ticket I am working on will not be in the viewable list of ticket tabs, and to find it I have to paginate right / left with the arrow buttons. The only way to close the ticket and clear it from my queue of open tickets is to click on the X of the tab, however.

It would be convenient to be able to close a ticket when working on it, rather than having to navigate through tabs to find the ticket in order to close it. Can you add a close ticket button to the ticket working view, so it can be closed/dismissed easily within the same workspace. Ideally this would remove it from currently open tabs at the same time (wherever it may be hiding amongst the many tabs I might have open).
