Comments could use native italics and links instead of HTML markup. More comment would fit on a line with a proportional font. Headings would be great for breaking up sections of code, and could be collapsible. Maybe linkable as well. Things that are arrays of arrays or tuples, like enums, could be tables. When you pass three functions to create an observer, there could be a table with columns "Parameter name, signature, implementation". Async code like observables and a thread's run method could be in a different font than code that executes right when you interpret it.
