We have some special buttons dedicated to global app settings and support. The buttons appear when you pass a callback to the dedicated methods.

ts.ui.Header
	.settingsbutton(function onclick() {
		ts.ui.Notification.success('Settings');
	})
	.supportbutton(function onclick() {
		ts.ui.Notification.success('Support');
	});

You can make them go away by passing null instead.

ts.ui.Header
	.settingsbutton(null)
	.supportbutton(null);

Here' an overview of the Navigation methods.
