I would like Codex/ChatGPT app to provide a rendered preview for Markdown files directly inside the app.
This request is not about Markdown rendering in chat messages, which already works. It is about previewing a .md file created or edited by Codex—ideally in a side panel or split view.
The preview should render standard Markdown, images, and LaTeX formulas, and update when the file changes.
At the moment, I need to open the file in VS Code or another Markdown viewer just to check the final result. An in-app side preview would make writing documentation, technical notes, and reports much more convenient.
Is this feature already planned or under consideration?
