MDyX is a WYSIWYM Markdown editor inspired by LyX — no raw syntax to type, but files stay plain, portable Markdown on disk.
Tables (with merged cells) and math formulas are edited directly in place. PlantUML/Mermaid diagrams render inline from source, so you're never toggling between a raw pane and a preview. Tables and diagrams round-trip via clipboard with spreadsheets and diagram tools.
