A great addition would be to have an Above the Fold button (ATF), this is to increase load speed and 'first paint' timings.
The AFT button would work by putting the elements CSS class inline in the HTML and prioritizes the content to load. This is a great way to increase speed, by Optimizing CSS Delivery. Google Lighthouse (Audits) have suggested this for my sites several times and have tried to 'botch' this but couldn't find a way.
The button would be a simple checkbox in the element settings tab.
