Currently, if you create a control that derives from RadTabbedWindow and then drag out a tab to create a new window, the newly created window is of type RadTabbedWindow. This feature will be useful if you want the newly created window to be the same type as the custom window that initializes the new window creation.
It would be great if there is an easy way to add some custom content after the tab items. Currently, this functionality can be achieved by modifying the template.
