Regarding the issue #3 , it seems that some images were too big for the size they were needed in the UI. I've reduced the sizes of some images and the HTML/CSS to use them properly. I've also noticed that the scroll performance issue was related to the CSS animation in the hero, and it looks like removing a duplicated animation set up was enough to make it smoother.
