WooCommerce Tabs [closed]

Yup, there’s a filter for it: woocommerce_settings_tabs_array:

add_filter( 'woocommerce_settings_tabs_array', 'wpse94969_settings_tabs_array' );
function wpse94969_settings_tabs_array($tabs){
    $tabs['catalog'] = __('Products','your_textdomain'); // or whatever you fancy
    return $tabs;
}

This will take care about the tab title itself:

The word “Catalog” appears again in two field labels below though.
To change these you can take advantage of the woocommerce_catalog_settings filter:

add_filter( 'woocommerce_catalog_settings', 'wpse94969_catalog_settings' );
function wpse94969_catalog_settings($fields){

    foreach ( $fields as $key => $field ) {
        if ( 'catalog_options' == $field['id'] )
            $fields[$key]['title'] = __('Products Options','your_textdomain');
        if ( 'shop_catalog_image_size' == $field['id'] )
            $fields[$key]['title'] = __( 'Products Images', 'your_textdomain' );
    }
    return $fields;
}
