Mac OS X Mavericks promises better multidisplay support, uses Apple TV as a monitor

We're in the midst of being shown new OS X Mavericks features here at WWDC, and one of those sounds especially interesting for those craving a bigger work area: for those already using a two-display setup, the dock and menu bar will now appear on either panel as your activity moves between them, and each display can be panned independently. What's more, if you have an HDTV hooked up to an Apple TV box, you'll be able to use that as a wireless third display in exactly the same way.
