One thing that you can do is build a Glist of all the items in the box,
gtk_widget_ref() each one, make the new box, add all the widgets to it, and
then gtk_widget_unref()... That could be done in about 10 lines of code I
think...

I second this motion. It would be very useful for several of my projects, and
might make some of the various gnome stuff a bit easier as well.
