I like how it’s done in Create React App:  * [ ] Show the URL only after successful compilation * [ ] Show network URL * [ ] Improve the UI Most likely we can reuse some functions from [react-dev-utils](https://github.com/facebookincubator/create-react-app/blob/dc4ce606ef8b4c97aec0c80c20f8116e9795bb21/packages/react-dev-utils/WebpackDevServerUtils.js) (we already use it in Styleguidist), then this task will be relatively easy ;-)
