I'm currently checking the feasibility of the tab controls included with ActiPro WPF Controls.
My current investigation is to see if my software can replicate the tab grouping behavior that is included in Chrome. From what I can see, the TabbedMdi host does everything I want except the ability to select multiple tabs and the ability to group them in the way I want. I can group the tool windows which have their own tab wells, but I want just one window that has groups within it. The behavior is similar to a 'dummy' tab that acts like a folder for other tabs, and when selected the inner tabs are shown.
Thanks for any insight you may have,
