Thanks.  I'll take a deeper look when I have time.  At first glance, the
name itself probably should be "markdown-ts-reveal" not "appear".  I'd
probably want to separate showing strict Markdown markup when markup is
hidden from the other features like math and evil/meow integration.  I
agree it appears (pun intended) that there is a lot of code for what it
does and not all of it is idiomatic ELisp, but that is separate from
whether it works or not.

+ Andrea Alberti who has a lot more LaTeX experience than I do and he's
contributed to the core mode with depth of knowledge.  I seem to recall
that he may have a similar "reveal" functionality somewhere and has, I
think, contributed a to-do list item to improve markup editing while markup
is hidden.
