$ionicConfigProvider is a provider that Ionic exposes and which allows us to do some very powerful configurations. We will not be writing any code for this as it is an advanced feature but you should be well aware of its existence.
Some of the features that $ionicConfigProvider lets you do, include the following:
Specify the transition type for your app
Set the maximum cache
Disable/enable animations
Enable/enable native scrolling
Specify tabs positions
These and many more are some of the features that $ionicConfigProvider lets you fiddle with. Remember that this feature is a fairly advanced feature and it is very likely possible to completely design your app without it. Most apps most likely do not use its features but if you find yourself ever needing to use it, you can visit the official documentation for $ionicConfigProvider to see its full potential at http://ionicframework.com/docs/api/provider/$ionicConfigProvider/.
