Integration with reselect-devtools

Hi! Thank you for this helpful app!

Is it possible to add [reselect-devtools-extension](https://github.com/skortchmark9/reselect-devtools-extension) from [reselect-tools](https://github.com/skortchmark9/reselect-tools)?

`reselect-devtools` is very useful if you work with derived data. They visualize the computed state tree.

It would be great if you can add it.

You can check how reselect-devtools work in this [demo](http://skortchmark.com/reselect-tools/examples/demo.html)
First you need to install their [chrome extension](https://chrome.google.com/webstore/detail/reselect-devtools/cjmaipngmabglflfeepmdiffcijhjlbb)
