Here my app.js code : 

```
Ext.Loader.setConfig({
    enabled: true
});

Ext.application({
    name: 'KP',
    appFolder: 'scripts/app',

    controllers: [
        'login.Login'
    ],

    views: [
        'login.Login'
    ],

    launch: function () {

        var view = Ext.widget('login')
    }

});

```

If I want to use some others views, controllers, models and stores in my application, should I define them in app.js? (like this : controllers[....all of my controllers.....])
Are there other way to get to work init function in my controllers? Thanks!
