We’ve been posting recently on some upcoming features being added to Actipro Ribbon for WPF that will be available in the upcoming WPF Studio 2010.1 release.
Today I’d like to show an interesting new feature where you can hide the title bar area of the Ribbon. Combined with other existing properties that hide the application button, hide the QAT, and prevent ribbon collapsing, you can achieve a standalone tab control that has full ribbon resizing capabilities in it for groups and group child controls.

This screenshot shows the result, which could be used standalone within any control. A new QuickStart has been added in WPF Studio 2010.1 showing how to do this.
Update: Just to clarify, this feature doesn't mean that Ribbon can be used as a tab control replacement. Ribbon can still only host ribbon groups and controls you'd normally host in a ribbon group. It's just showing how the title bar area where contextual tabs and the QAT would normally be are hidden with a new property. And in this particular sample we hid the application button as well.
