I made (yet another) Markdown editor because I couldn't find a native, macOS-first, file-based (i.e., not folder/vault-based) WYSIWYG Markdown editor / Typora alternative that feels like it's made by, or at least for, Apple. It's especially painful since I'm spoiled already by CotEditor when it comes to text editors...Hence, Edmund.
To be clear (and a bit redundant), Edmund opens plain GFM .md files with live preview...Using AppKit + TextKit 2 + Swift, with WebKit ONLY for read-mode. I'm still developing more features such as file outline, basic folder support, extensions system, etc. The full roadmap is at https://trello.com/b/vw2TveNI if anyone's interested.
Would appreciate any form of feedback (or contribution) :D
