Great work! Lots of little improvements to be made but its a great start. I am glad its in AngularJS and open source, looking forward to see it under the hood.
As for the init() function, the tutorial I saw mentioned it, and although I know it's unecessary, I liked the way it encompassed the functions called at initialization. But you're right, I'll probably delete it later.
If you have other suggestions or resource to share, feel free to tell me. Thanks.
