system.windows.controls.ribbon

I'm using "Microsoft Ribbon for WPF" and creating multiple RibbonTab. I cannot figure out a way to view/focus different tabs in the designer and it by default show the "Home" tab. To see design/xaml changes I made to tabs other than the "Home" tab, I have to debug the project every time and click through the tabs, which is not very convenient. Or I can command out the tab xaml I want to to ignore. Anyone body out there has a solution? You can also use the SelectedIndex property on the Ribbon to set which tab is the currently selected tab (0 being the first tab, 1 being the second, etc.)
