keeping external links in Fullscreen

I really love this plugin! Is there a way I could keep my external links in the fullscreen view instead of opening mobile Safari? All of my internal links work great. It’s just the ones that take me to a new page. I need them to go to a separate page from the browser but would like to keep it contained to the fullscreen mobile app for mobile devices. Thanks in advance.
