MEO adds a proper editing mode to VS Code. You get a live/source toggle in a single tab, a floating toolbar for formatting, inline table editing with live cell previews, full-screen Mermaid diagram rendering, a document outline sidebar with drag-and-drop section reordering, and optional auto-save. No new app to switch to, no split pane.

One thing most markdown extensions miss: it preserves VS Code's native diff view, so reviewing git changes in a markdown file still works exactly as expected.

Git diff and vim keybinding support are coming soon.

Built on VS Code's webview API and CodeMirror.

Happy to answer questions.
