Having problems with dapp lite

Hey guys. I was trying out dapp lite and was having a weird problem. I could not add another page to my app because the edit button on the project menu for that app was gone, I could only view the page that I had first made. I have tried swiping to try to find it, and exploring my touch. What am I doing wrong? Also, how do you add files to the movie player? I have some files I would like to add, but when I press content it just says files heading and there's nothing there. Also, is there an object for statistics that move by doing actions, (for example if I was doing a pet game the hunger stat would move up when you pressed the feed button)? And what are the differences between dapp and dapp lite? Thanks!
