Add a close button in the "search tabs" (sub-menu of "list tabs" button).

You already added a close button to the "list tabs".
It is necessary, now, a close button to the "search tabs" items listed.
Many people uses lots of tabs, and the close button in the items showed on the results of the "search tabs" function will aid to organize the navigator.
Thanks a lot.
