+## Tabbar
+Every tab has its own navigation bar. However, if you do not set its parent `<Scene tabs={true} />` with `hideNavBar={true}`, the tabs' navigation bar will be overrided by their parient.

 Your scene `component` class could implement _static_ renderNavigationBar(props) method that could return different navbar depending from component props
