Hi,

1. If so you need to rewrite this function named “sf_wishlist_button” found on \wp-content\themes\cardinal\swift-framework\core\sf-woocommerce.php alter the <i class="ss-star"> word and give your own words in that place on line #275 or you can copy that function and alter the changes and put that in the child theme’s functions.php to save the change from updates 🙂
2. You can enable the sidebar in the category product pages and use the Woocommerce layered nav widget to display filter options.
4. You can try to change the heading style of page Heading in Theme Options -> Woocommerce Options -> Shop Options -> WooCommerce Page Heading Style

Let us know,

Thanks,
laranz.
