Very useful, and convenient that you can immediately close any tabs right from the popup window!

This is awesome! Some minor gripes - for example, if I search for "goog" it will show any tabs with a "g" and an "o" in them. Also, the first tab in the list should ideally be the most recent one.. A request - it would be awesome to be able to customise the Alt+W shortcut to close tabs - personally DEL would be better!
