How can I add widgets to the category page?
How to add/save/retrieve additional fields to all available widgets?
That is not native behavior of it. If you check the source of WP_Widget_Categories $title = apply_filters( ‘widget_title’, empty( $instance[‘title’] ) ? __( ‘Categories’ ) : $instance[‘title’], $instance, $this->id_base ); The title comes exclusively from the value saved in instance (or default if not).

Numbers are not allowed … Read more
