**Do you want to request a *feature* or report a *bug*?**

Feature.

**What is the current behavior?**

The new DevTools doesn't show the component file path as did the v3 version.

**What is the expected behavior?**

It would be great to show the component file path, it's a really important feature when working in a large codebase.

**Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?**

React DevTools v4 is affected, v3 had it.
