Currently you can only open in a new window or close an individual tab or all of the tabs in a window.
I would love to be able to drag and drop a specific set of tabs. Eg. I select 3 out of 10 tabs and close them. Or select all but one of the tabs and make them linkset A.
Google chrome does a great job of allowing quick and easy tab dragging, dropping and closing, you can shift+click or ctrl+click multiple tabs to drag, close,
