Viewing Tabs

Just an idea: what if there were a cool, quick way to look at all the tabs open in a browser session (for any browser, but personally I'm interested in Chrome or IE8). It could be Expose-style where a quick shortcut key shows you thumbnails of all the current tabs, or perhaps Aero-peek style where you can a thumbnail of them as you go over the tab. This would be extremely helpful for long sessions where you have many things that you're going back and forth between. Personally I would find it exceptionally useful when I'm doing research on scientific journal articles and I find myself looking back at certain pages often while reading others.
