Do you know what this strange looking button does that sits next to your tabs in IE7? Ah smarty pants read the title – yes it will show you all thumbnails of all your open tabs on a separate page. This comes in very handy all the time while we peruse through twenty or more opened tabs. A friend was watching us work and she was all like wow how did you do that. And I was all like watch… And I clicked the good click on the magic box and up popped all of my tabs.
tab IE7 Tip: Show me those tabs!

So this little documented and HIGHLY recommended button sits to the left of your tabs. It looks like 4 small rectangles in a mini-tab. Do you know what it does?? It gives you an Aero-esque albeit flattened but still functional (and uses MUCH less memory). It shows thumbnails of all of your open tabs and lets you select where you want to go.
