Customizable abstract view

Hi all.

I am redesigning my app and I have a problem. I used a “main menu” page which had left and right sidemenus. The navigation was not what I wanted and I’ve decided to implement sidemenus to all the pages in the app, using an abstract view.

My problem is that I want to customize the nav-bar. the “default” navbar, which is defined in the abstract view, has only a simple ion-navicon icon in the left side. How can I add more icons on the nav bar in a child view?
