Yes, we should do that. In the embedding prototype I have a class called
GladeTab which is similar to your description of GladeProjectLayout. It
is a GtkVBox subclass. Each GladeTab parents a GladeDesignLayout, and is
also associated with a specific project. GladeTab is meant to be used in
conjunction with a GtkNotebook, but it most certainly can be used
without one.

Ok, so a GladeProjectLayout/GladeTab object would solve most of our
problems with regard to API and would satisy most use cases. Now what
sane API would we need for client programmer to put an arbitrary
GladeWidget into a GladeDesignLayout? 

How about this:

  /* if widget is NULL, remove current GladeWidget */
  glade_design_layout_put (GladeWidget *widget);

of course this function would only make sense if `widget' refers
to a toplevel or parent-less GtkWidget.
