ADD gchar **extra_label TO struct ZenityData

	this is done to keep the name of the extra buttons

ADD general option "extra-button" with string array as argument

	This will upon consecutive calls save the name of buttons in an array of strings

To all MODES, except notification.c and about.c ADD
  if (data->extra_label) {
    gint i=0;
    while(data->extra_label[i]!=NULL){
      gtk_dialog_add_button (GTK_DIALOG (dialog), data->extra_label[i], i);
      i++;
    }
  }

	This add the extra buttons to the dialog. The response is the number of the button

To all MODES response, except notification.c and about.c ADD
    default:
      if (response < g_strv_length(zen_data->extra_label))
        printf("%s\n",zen_data->extra_label[response]);

	This will print the button name to stdout when they are pressed

ADD question option "switch"

	This will suppress the standard "ok" and "cancel" button in question. This just wort in combination with --extra-button, otherwise error is raised.
