So cool to see one of my favorite products on here. Overleaf's rich text view is a total revolution for LaTeX editing and I've always wondered how it combined MathJax with an editor. Love this product.
What was so cool recently was that a group of 7th/8th graders[1] used us to write their 300-page engineering notebook!! Just amazing :)
