Please add a close button next to a highlighted tab under "list all tabs".
Also, if you use multiple windows with their own tabs, allow sorting tabs order by window launched from (if I click list all tabs in one window, list only those tabs in the same order they appear in my tab bar).

Also, an extension of this idea is to add an X - close icon button on the left side of the search result list after we click search tabs from the List menu buttons.
