Markdown, Quardown, Typst, this and that. This looks to LaTeX. All of this became so confusing and un-standardized - I went back to HTML+CSS.
Well basic markdown is super useful to do stuff quickly. Problem is when people started to build systems upon systems upon something that should not be used for more complicated cases. Maybe not a problem because I don't care but I just see how loads of things that someone created to be "just that" someone takes without understanding and builds on top instead of understanding limitations and scope of the initial idea…
Regarding Notepad, keep in mind they dumped an entire separate app (WordPad) by merging the ability to format into Notepad. This kind of mirrors what I was talking about above: one app with a very low floor but a flexibly high ceiling when you want to go there with it rather than two separate apps you need to pick from up front.
