Let's imagine, that user opened three browser tabs with my app. One of them is unprotected and there is some unsaved user input (tab1). Other tabs (tab2,tab3) have protected resources.

问题 Hi, I'm about 2 weeks into building my application with ember.js, and the time has come to pull together my project layout into its final shape.
