I just discovered Augary, a Chrome Plugin for debugging angular applications. I can't believe I never came across this before.
Install Augary and then an Augary tab will appear as part of the Chrome Debugger tools. Here it is for the Learn With application:
Instead of trying to unravel the application through compiled source files and some guesses, Augaray models out the application for you and allows you drill into services, components, and routes to give you a deeper understanding of what is going on in your Angular application.
I've been playing around with it and it is pretty awesome.
