I absolutely love this website but it's a resource hog! Being an web dev myself, the size of your core JS is outrageous. The website performs fine on my laptop, but my iPad mini (1st gen) struggles and Safari often crashes when using the site. I don't want to sound condescending or patronising, but I can't figure out which functionalities would require so much resources.
I know this is a very broad "bug" report, but I think we'd all like some feedback on whether or not you're working on significantly improving our experience.
