More Sorting Options for WooCommerce

Pablo Pacheco: I love your More Sorting Options for WooCommerce plugin which has saved my life on the shopfront. At the bottom of the page (link above) you gave “BigFrank” a short plugin – https://ufile.io/j30xe (that made BigFrank very happy) to enable products to be sorted by SKU on the product pages in woocommerce as well without having to click on the arrow every time. Unfortunately the plugin is no longer visible at that site. Where can I find it, please? I have over 700 products which show in the order they were uploaded which is not what I need and I keep having to use the wretched arrow to get them into SKU order which is very time consuming. Many thanks for your help.
