Before we have a function as long as the page is a picture of the individual against the center of the navigation bar, the other using the default navigation bar, I find a lot of articles, all about global settings, in the next window in app.json Add "navigationstyle": "custom", so you set the picture and also can go to the top, but this is a global style, the program comes with a small effect there will be no return, more trouble.
Add their own "navigationstyle" in json in the pages: "custom" phrase, there is no effect from the last communication and colleagues for a moment, try the side, a success. It is so wonderful.
