Cool project! Also check out rich text support in OutlineEdit 3: https://outlineedit.com/ It has an embedded plain text representation of all rich text formatting that is based on html-style tags and can mix and match all combinations of formatting styles. Also supports macOS versions back to 10.14 Mojave. - Source: Hacker News / over 1 year ago

Markdown is awesome! But, when writing 1000 words+ articles, I quickly feel the need for a better experience. For years, I’ve used StackEdit — an open-source, in-browser Markdown editor — for editing all kinds of long-format Markdown text. That said, given my recent experience with WYSIWYG editors, I thought I could do something better. - Source: dev.to / 11 months ago

This is especially annoying as when I export from stackedit.io to HTML, then it just cuts off anything which is outside the greyed in code window! Source: 11 months ago

StackEdit[0] pretty much perfected what I needed out of a markdown editor - I just need somewhere to write my tickets/docs that wasn't Github so that I could format it properly while writing. I still use it from time to time [0]: https://stackedit.io/. - Source: Hacker News / 12 months ago
