As we make further progress on our docking window and MDI product for WPF that will be added in Actipro WPF Studio v4.0, we've started to add some new themes. 

The screenshot shows the newly implemented Office 2007 blue theme that will be part of Docking for WPF upon release.  It will match perfectly when using it with our other WPF products, like Actipro Ribbon.

The final RTM version of Actipro Docking for WPF will include several themes that can be applied with one line of code.
