Does anyone know how to save a program so I can go back to it after I close the app?

Go into direct, tap the 'save' option at the top of the keyboard, write the file name, enter. I think that's what you meant?

Or HOLD your L button. The tab will change to just SAVE, tap that, and you can enter your file name intuitively :)
