How do I get Safari to search all tabs from all Safari windows in the Tab Overview, instead of only those in the current window? When I press the shiftcommand\ keyboard shortcut, it goes into 'expose' mode and allows to search thru only the tabs in the current window, not all windows. 

It would be super handy to be able to search/display tabs from all windows.

Is there a way to do this?
This extension: http://nickvdp.com/tablist/ does allow global search and is awesome. It would also be good if it included iCloud tabs.

I would love it more if it could be invoked from the keyboard or integrated into Spotlight but it's still incredible. The way it just brings that tab+window directly to the front is beautiful.
