Yes, I hadn't looked at it that way. That's not what one generally expects,
however, when clicking on the header. You could implement that in
TreeVirtual reasonably easily, I think, by catching a click event on
something (header, a button, whatever) and sorting the data model on
whatever criteria one wanted. Given that there's no standard, expected
behavior, I don't think I'd add this as a standard feature, though.
