CakePHP static pages (without entity) but with dynamic content

I have a few pages that is not connected with entities (index page, terms of use page, email page).

Detailed description: In CakePHP, when you want to have a static page (such as index for example), you should use the PagesController (not connected to any entity). However, my static pages have dynamic content, as the index page (the navbar is dynamic: it has the name of the user when logged in, and special buttons).

1st: To do this, I create a CustomStaticPagesController controller (which is not connected to any entity), in which I created the methods (index, email, termos-de-servico).

2nd: I edited the routes.php references to the actions without the standard localhost/controller/action now this localhost/action.

Question: How can I improve (do it right) the two points referred to above? Any other point to improve ?

CustomStaticPagesController controller code:
