Live/source toggle for markdown in one tab beats VS Code's split-pane hell.

Strengths

•Solves real friction: no context-switching between raw and preview, single-tab UX
•Preserves native diff view for git changes—thoughtful integration with VS Code workflow
•Markdown-specific features (inline tables, Mermaid rendering, outline sidebar) go beyond generic editors

Weaknesses

•Markdown editing extensions are crowded (Markdown All in One, Markdown Preview Enhanced, Foam)—needs adoption proof
•Only 8 installs suggests early traction; reliance on VS Code webview API limits extensibility

Post Description

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.
