[This commit](https://github.com/gaearon/redux-devtools/commit/0a2a97556e252bfad822ca438923774bc8b932a4) should give you an idea about how to add Redux DevTools for your app **but make sure to only apply `devTools()` in development!** In production, this will be terribly slow because actions just accumulate forever. (We'll need to implement a rolling window for dev too.)
**You can build a completely custom UI for it because `<DevTools>` accepts a `monitor` React component prop.** The included `LogMonitor` is just an example.
Some crazy ideas for custom monitors:
* A slider that lets you jump between computed states just by dragging it
* An in-app layer that shows the last N states right in the app (e.g. for animation)
* A time machine like interface where the last N states of your app reside on different Z layers
* Feel free to come up with and implement your own! Check `LogMonitor` propTypes to see what you can do.
