	group = Ti.UI.createTabGroup();


	var windowFactory = function(options) {

		this.win = Ti.UI.createWindow({
			title : options.title || 'Window 1'
		});

		this.win.addEventListener('swipe', function(e) {
			Ti.API.info('swipe fired x ' + e.x + ' y ' + e.y + ' direction ' + e.direction);
			if(e.direction === 'left') {
				var newWindow = windowFactory({
					"title" : new Date(),
					"tab" : e.source.tab
				}).win
				e.source.tab.open(newWindow)
			} else if(e.direction === 'right') {
				e.source.close();
			}
		});
		return this;
	}
	win1 = Ti.UI.createWindow({
		title : 'Window 1'
	});

	win1.addEventListener('click', function(e) {
		group.activeTab.open(windowFactory({
			"title" : new Date(),
			"tab" : group.activeTab
		}).win);
	});

	win2 = Ti.UI.createWindow({
		title : 'Window 2'
	});

	tab1 = Ti.UI.createTab({
		window : win1,
		title : 'Tab 1'
	});

	tab2 = Ti.UI.createTab({
		window : win2,
		title : 'Tab 2'
	});

	group.addTab(tab1);
	group.addTab(tab2);

	group.open();

}).call(this);

cool idea

Do you know in iOS 8 how can I get the native behavior with a custom leftNavButton in my window (into navigation window) Thanks!
