Congrats to the new editor, I really like it!
I wanted to chime in to say that in contrast to others I really like the new design decisions you took regarding the header and general markdown markup. Yes, header hierarchy may be a bit harder to parse visually, but it’s so much cleaner and easier on the eyes all the time I’m not trying to see whether I got the heading levels right (which is 99% of the time I spend in the editor). Also really like the way the markdown markup is colored in light grey, making it visually disappear, and also how checkbox items fade after being done (also way less noisy than a solution with strikethrough). So great overall , I look forward to using it!
