Users appreciate Extendify's extensive library of beautiful patterns and templates, which makes website design easy and visually appealing. They commend the plugin’s flexibility; deactivating Extendify does not break the site as it allows for CSS retention. This feature is highly praised for its ease of use, making it the best way to build WordPress pages, especially with the native Gutenberg editor. However, users note the plugin's icon is unclear and suggest improvement. Overall, Extendify promises to simplify website creation and is particularly effective for quick landing page builds and future inclusion of WooCommerce blocks.
