easy way to do operations on many items selected in a list in a similar manner to how the Mail app on iOS works.

app.js

Ext.application({
    name: 'MyApp',

    requires: [
        'Ext.MessageBox'
    ],

    views: ['Main'],
    launch: function() {
        // Destroy the #appLoadingIndicator element
        Ext.fly('appLoadingIndicator').destroy();

        // Initialize the main view
        Ext.Viewport.add(Ext.create('MyApp.view.Main'));
    },

    onUpdated: function() {
        Ext.Msg.confirm(
            "Application Update",
            "This application has just successfully been updated to the latest version. Reload now?",
            function(buttonId) {
                if (buttonId === 'yes') {
                    window.location.reload();
                }
            }
        );
    }
}

views_main.js

Ext.define('MyApp.view.Main', {
    extend: 'Ext.tab.Panel',
    xtype: 'main',
    requires: [
        'Ext.TitleBar',
        'Ext.Video',
        'Ext.List',
        'Ext.data.Store',
        'Ext.ux.plugin.ListActions',

                actionsToolbar: {
                    items: [{
                        text: 'Delete (0)',
                        ui: 'decline',
                        eventName: 'delete'

                },
                actionToggleButton: {
                    selector: function(list) {
                        return list.down('button[name="listactions"]');
                    },
                    enableText: 'select',
                    disableText: 'cancel'
                }
            }],

            data: [{

            },{
