I recently discovered Zettlr and frankly I'm pleased enough with it: cross-platform, does the job well-enough. You can always use an extension for VSC or emacs,etc. but when simply wanting to read a markdown file I use this one. Previously I tried Typora and others but I'm not willing to pay for a markdown reader. Maybe for an editor, whenever I'll decide writing (though I'd use emacs 9/10 times)
