Users appreciate the “Responsive Sliding Menu” plugin for its straightforward, quick, and practical functionality. It performs as promised and is particularly useful for those dissatisfied with Gutenberg's navigation block, providing a sliding menu feature that integrates well with Full-Site-Editing block themes. Users also commend the responsiveness of the developer, who quickly addresses issues. However, the plugin has some drawbacks, including an annoying "leave us a review" nag banner with non-functional buttons and some UI issues, such as the settings window moving off-screen, leading to difficulties in editing. Despite these issues, it is highly recommended for its core functionality.
