Hi there,
list of all scripts that GP may load. Note they only load if a) the option is enabled in the theme and b) the template being viewed requires them ( eg. blog masonry only loads on blog and archives ):
Default Mobile menu
/wp-content/themes/generatepress/assets/js/menu.min.js
Off Canvas
/wp-content/plugins/gp-premium-master/menu-plus/functions/js/offside.min.js
Navigation Search
/wp-content/themes/generatepress/assets/js/navigation-search.min.js
Sticky Nav:
/wp-content/plugins/gp-premium-master/menu-plus/functions/js/sticky.min.js?ver=2.2.1
Blog -> Infinite scroll
/wp-content/plugins/gp-premium-master/blog/functions/js/infinite-scroll.pkgd.min.js
Blog Masonry
/wp-content/plugins/gp-premium-master/blog/functions/js/scripts.min.js
Which has a core dependency: /wp-includes/js/masonry.min.js
