2. **Automatic out-of-stock display**: Enable automatic display of out-of-stock items, eliminating the need to manually toggle the out-of-stock option. This ensures that out-of-stock items are not overlooked.
3. **Product code display feature**: Display the product code (management number) below the product images, allowing users to view and copy the product code without having to open each product page.
