I want to this to work!

I like the premise and all the components are in place, but this is really more a 0.8 version than a 1.0.
(Not if you want this to work you will have to make sure to create an API key for the Google Driving Directions API). The app will not show or confirm you have a working key or not. )
For Woocommerce it TECHNICALLY works, in that it allows you to pick orders and add them to your route. But what it DOES NOT do is figure out the route your should be taking between those adresses. Second – the ‘route document’ that is created does not have ‘driving directions’ it merely shows the map and the different points in between.

So it really doesn’t help with either PLANNING or DRIVING, unfortunately, unless I completely missed something.
