Does it mix well with text input? What I really want is a native WYSIWYG Markdown editor - in a similar fashion to Typora (Electron) or Milkdown (a JS library).

Blitz has good plaintext text input support. But there's no contenteditable (which is what you would need for rich text editing) yet.

litehtml appears to have no built-in text input support so far as I can see.
