Open tab in new window Rated 4 out of 5 stars

I sometimes need to see two pages side by side. Therefore it would be great to have a menu item like "Open tab in new window" -- possible? This is increasingly useful with all those web applications out there, like GoogleDocs, blogs, etc where I need to compare text, data. Like on the desktop where you can have multiple windows open side by side...
