MEO - a Markdown editor for VS Code with live/source toggle

I write a lot of markdown alongside code: READMEs, specs, changelogs. VS Code's built-in experience is either raw syntax or a read-only preview pane you have to keep open in a split. Neither is great for actually writing. 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.
