ASP.NET Ajax-aware JavaScript IntelliSense

A new release of Visual Studio "Orcas" shows off the intellisense features nicely, including:

Proactive Completion List: No more waiting for '.'
Keywords in Completion List: fun your way to function
ASP.NET AJAX Concepts in Completion List: Direct support for Atlas
IntelliSense from Script Libraries for ASPX Pages: Now you can see objects that exist in other external script files
This comes along with the release of an updated Ajax Control Toolkit.
