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, full-screen Mermaid diagram rendering, a document outline sidebar, 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.
Built on VS Code's webview API.
Happy to answer any questions about it.
