Hey there Sailorlion,
I apologize about the late response, thank you for being patient! Were you able to figure out how to add those apps to your front screen? If not, I'd be happy to help out! Now, if you go to the "Your Apps" screen, scroll to the right and select "See all". From there, find the app you want to appear on the front screen, and hold down the select button until an option menu appears. From there, select "Move" and drag the app to the "My apps" section. That's all there is to it!
I hope that helps you out, and if you have any other questions or concerns for me, please let me know.
