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?
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.
