File viewer in desktop app shows raw markdown instead of rendered formatting

Summary

The file viewer in the Claude Code desktop app shows .md files as raw text, including visible #, **, and other markdown syntax. There doesn't appear to be a setting to toggle rendered formatting.

Why this matters

A large share of what Claude Code reads, writes, and displays is markdown: session outputs, agent reports, PRDs, READMEs, design docs. For many workflows the file viewer is the first place a user reviews what Claude has produced. Displaying raw markdown there makes the output harder to skim and review, and often sends users out to a second editor (VS Code, Cursor, Obsidian) just to read a file the desktop app already knows how to open.

Given that the preview pane already renders HTML, PDFs, and images, rendered markdown in the file viewer feels like a natural extension.

Request

Add rendered markdown display for .md and .markdown files in the desktop app's file viewer. Ideally with a toggle between rendered and raw views, since editing tasks still benefit from seeing raw syntax.

Current workaround

Right-click → Open in → external editor. Works but breaks flow, especially when reviewing multiple files Claude has written.
