Hi James, this looks great. The blocks remind me of Notion (in a good way) and I'm excited to write some tutorials.

One nitpick: I started test driving writing a new course and the template is, I believe ironically about homeopathy, but as someone whose close family has gotten inextricably entwined in "alternative" medicines, I would appreciate a more standard lorem ipsum or a "how to tie your shoelaces" template instead. I think this aversion would apply for a lot more folks, too.
