Just wanted to say, I enjoyed the article and your minimal rich text editor library looks great! I've been working with heavily customized code editors (mostly CodeMirror from previous major versions to current) and rich text editors (Quill, etc.) for years now, off and on. For various reasons I keep coming back to building a new editor, sometimes in the terminal for a REPL with syntax highlight, or a Markdown editor in the browser, other times attempting a content editor with media blocks. CodeMirror and ProseMirror are impressive works and my current go-to libraries, but I'd love to try a light-weight approach from the bottom up, small enough to be able to understand it completely.
