you can add following network dashboard widget in previous plugin test out:

add_action( 'wp_network_dashboard_setup', 'dashboard_setup_so_23713801' );  function dashboard_setup_so_23713801()  {     wp_add_dashboard_widget( 'widget_so_23713801', __( 'test widget' ), 'print_widget_so_23713801' ); }  function print_widget_so_23713801()  {     b5f_print_recent_posts(); }
