this is dope.

Some feedback:

- while I am going through the chapters i keep trying to highlight certain sentences so i could bookmark them for later, itd also be great to do cmd+f to search keywords

- in chapter 1, the "under the hood" link crashes the app

Thank you! I'll fix both of these pronto

the datavis here and type hinting (even if it's just default swiftmath) is really nice.
