    Hi,

    Could you consider using passive listeners to improve scrolling performance?
    This is the feedback I get when running a site with the plugin through PageSpeed Insights referring to /wp-content/plugins/simplelightbox/dist/simple-lightbox.min.js line 0:

    Does not use passive listeners to improve scrolling performance
    Consider marking your touch and wheel event listeners as passive to improve your page’s scroll performance.

    Thanks!

    Kenneth
