Collapsable NavigationBar and Header Controls

EyeFinder is great, especially since it now supports Office2007 rendering.  It would be nice to have the collapse feature like Outlook 2007's equivalents to HeaderControl and NavigationBar have.  Please correct me if they already do this somehow.

Here here, I would love to see the 2007 collapsable naviagtion bar and Header Controls, and did anyone notice how the tops of the countrols are slightly rounded, THATS QUALITY, such attention to detail.

I would love such feature, too.

There's an example posted by one of our customers in the Eyefinder forum, where they have constructed such a control based on Eyefinder:

That is to collapse the groups, but we are looking to collapse the whole outlook 2007 bar see https://www.devexpress.com/Support/Center/GetSCAttachment.ashx?id=74f6c7bf-0b67-47e5-995d-850412380725
