I created a Windows Phone 8 app using AppStudio. I then generated it and downloaded the source. I want to change the font size and other properties of the main header text for the panaroma control (the largest text found at the top of screen). I tried changing the TextBlock properties in the xaml for the individual views. There is one view per panaroma control "column". But when the app is run, the main header text still appears the same. How do I change the main header text for the panaroma control?
