You could use ng-checked for settings view.

@Pitros i'm not too familiar with ng-checked. I'll give it a try and see what i can do.

@Pitros I switched it to ng-checked 👍 Thanks for the heads up (I misunderstood what ng-checked was for initially)

[Pitros]

Now it looks simplier 👍 , ng-model on input probably should work as well but that's a quick note.

Looks good @jakejarrett thanks for working on this.. pretty cool feature.

I'm just going to do some refactoring although everything works great.
