@Pantherina "I mean notes should have bold headers, not hashtags." OK, but that reflects what *you* want from a notes app, not what everyone wants. And of course that's totally fine, you can get that from a notes app that has WYSIWYG formatting if you find that it works for you. But I would suggest that it doesn't make sense for you to enter a discussion about a Markdown notes app and tell a bunch of people, for many of whom that app probably works pretty well, that they're making a bad choice to use it because it doesn't offer the behavior you want.

For what it's worth, I think a lot of people use Markdown notes apps in a way that you might not be considering. Like, this separation between writing and viewing that you're talking about simply doesn't exist in my note-taking workflow. I usually just read the raw markup, possibly with some minimal formatting added on by whatever app I'm using.
