I\'m not talking about the vista glass feature, I already know how to accomplish that. The feature that I\'m talking about is add controls to the titlebar, like office 2007
Joe Castro, a WPF product team developer, has an MSDN code gallery project called "WPF Chrome" that can be used to create an office 2007-like UI (ie: controls that span both the client, and non-client areas of a window).
