Stock Based Sort-by option in Category Pages

In a category page product with In-Stock should come in the top of the categories product list rather than out-of-stock products. No having this option is extremely disappointing, I made the initial request about 7 months ago but still not even an update on this.

We have about 300 products in a category and the out of stock products are occupying the top of the list in all categories, this is making the customer to scroll through the category to find the In-stock products. THhis issue is making us to manually check & remove the out of stock items from categories itself & re-adding them when the stock is available again.

Your team should understand that a business is using an ecommerce website to sell products but we cannot do that by showing out-of-stock products in the top of the list.
