Include history.length in redux state

[XuluWarrior]

The history object has a length property which isn't reflected in the redux state.

I want to add a simple back button to my electron app and knowing when history.length == 0 would allow me to disable the button.

I have a similar issue, where I am trying to implement a back button. I also would like to read all previous urls in the history, if that's possible.
