Where specify the controllers, models, views and stores to load?

Hy,

Where to specify the controllers, models, views, stores the application has to load?

1. Just in the object Ext.application ({

controllers : ['Users'], models: ['User'],

views : ['user.Edit'].

stores: ...

})

2. I have seen examples where in controller objects you specify models, views and stores

Is there a better approach? I think the option 1 is more centralized and better, right?

Thanks
