It would be nice to re-order verses by dragging the tabs in the notebook. While it is easy to enable dragging the tabs, the code below fails to actually re-order the verses for the reasons explained.

// this doesn't work because page_num is the new position, ie it is pos
// we have to go through the list parsing "Verse %d" from the label to get pos and
afterwards re-write all the labels in the new order.
static void
reorder_verse (GtkNotebook *notebook,
               GtkWidget   *child,
               guint        page_num,
               DenemoStaff*     thestaff)
    GList *children  = gtk_container_get_children (GTK_CONTAINER(notebook));
    gint pos = g_list_index (children, child);
    GList *this = g_list_nth (thestaff->verses, pos);
    thestaff->verses = g_list_remove_link (thestaff->verses, this);
    thestaff->verses = g_list_insert (thestaff->verses, this->data, page_num);
    g_list_free (this);
    g_print ("Reordered %d as %d\n", pos, page_num);

 gtk_notebook_set_tab_reorderable (GTK_NOTEBOOK (notebook), gtk_widget_get_parent (textview), TRUE);
  g_signal_connect (G_OBJECT (notebook), "page-reordered", G_CALLBACK (reorder_verse), staff);
