Jumping on the landing page conversation. My idea of a perfect page would be an alphabetical index with a link to the tutorial whether it be a master class or in creative scrap/lab.
The scrolling to find what I want gets old especially with the amount of information on (for example) the master class page.
If it can’t be one page for all, even an alphabetical list at the top of the page with the link to the tutorial would help. There would not be as much scrolling through a text index to find what a person wants. This would work for both master class and creative scrap.
Just my humble opinion!
