Here’s a great tip from the geniuses over at Lifehacker, now you can enable Aeropeek in Windows 7 so you can get preview of each tab rather than each Window (much like ie8 supports)
If you want to enable it, all Chrome builds (including the stable build) will let you add the flag –enable-aero-peek-tabs after the quoted path in the shortcut on your desktop or in your taskbar (if you hold shift when you right click you can go to properties and add it there).
This is very handy if you’re anything like me with one window but lots of tabs open at once.
