Hey! Happy to take this on.

Approach:

1. Add electron-devtools-installer as a dev dependency and create a src/main/devtools.ts helper that imports { installExtension, REACT_DEVELOPER_TOOLS }.
2. In src/main/index.ts, after app.whenReady() resolves (and only when NODE_ENV !== "production"), call the helper to install React DevTools once and log success/failures via electron-log so developers can diagnose headless installs.
3. Optionally expose a “Reload React DevTools” menu entry in src/main/menu.ts so folks can re-open DevTools if they closed them.

Questions:

• Is it OK if we auto-install every time pnpm start runs, or would you prefer an opt-in flag/env var?
• Should we guard this behind platform-specific logic, or do you want Windows/Linux devs to get the integration too?

Thanks!

Great, @Karan-05! Sounds like a great plan to me.

I think it's ok for now to install during pnpm start - we can tweak it later if need be.

Perfect, thanks for confirming @setchy! I’ve wired it up to install automatically on pnpm start across macOS/Windows/Linux, and added a menu option so we can re-trigger the install manually if needed. I’ll open the PR shortly once I finish lint/tests.
