Support for interactive TabHeader content (i.e. Buttons, Checkboxes) that does not invoke the tab selection and is aligned next to the tabs

It would be nice to have an own configuration block for the selected item styling. This could be similar to the header template configuration.

Presently the TabView only supports unbound mode and there is no way to bind a list of items from the view model to display as tabviewitems. It would be convenient if there is an ItemsSource property.

At the moment when clicking the overflow button, a list of items is displayed in a Popup. It would be convenient if there is a built-in mechanism for defining a custom action upon clicking the overflow button. For example one might want to open a SideDrawer.
