The plugin takes a no-frills, zero-config approach – you simply activate the plugin, and it just works – thanks to the excellent underlying web component implementation. There should be no notable adverse effects on performance, also given the plugin uses the <a href="https://make.wordpress.org/core/2024/03/04/script-modules-in-6-5/" rel="nofollow ugc">WordPress Script Modules API</a> that was introduced in WordPress 6.5.
The plugin respects user preferences for reduced motion, as a best practice for accessibility.
