Make the product category permalinks non hierarchical. So instead of `shop/clothing/t-shirt/` we'll see `shop/t-shirt/`

non-hierachical-category-permalinks.php

<?php
// make the categories non hierarchical for their permalinks
function my_woocommerce_taxonomy_args_product_cat( $args ) {
	$args['rewrite']['hierarchical'] = false;
	return $args;
}
add_filter( 'woocommerce_taxonomy_args_product_cat', 'my_woocommerce_taxonomy_args_product_cat' );

Hey, does anyone know how to add a filter to include blog posts and pages? So that this setting works globally across wordpress?
