The "Advanced Product Filter" module enhances the OpenMage/Magento Admin product grid with advanced filtering capabilities. It introduces a new button in the Admin > Catalog > Products grid that, when clicked, reveals a fieldset. This is similar to promo rules and allows users to filter products using all available product attributes.

• Advanced Filtering: Harness the power of product attributes for more nuanced product search and management.
• Compatibility: From our tests, this module is compatible with most plugins available for OpenMage/Magento.
• Intuitive User Interface: Adds a new button seamlessly into the product grid for quick access to advanced filters.
