That's the one - working on a lot of improvements at the moment (thanks for asking!). Lots of exciting things we can do to make writing great content easier for our authors, and the reading experience great for our customers across the board. Usability and overall quality are a key focus going forward.

This type of content makes it really easy to clearly demonstrate how you can think about your target audience when creating a product. Really important to get right when structuring and editing a technical book.

It's awesome! Surprised it wasn't already submitted :).
