Nothing is submitted. Progress saves on this device, so a second sitting picks up where the first stopped. Tap any step number to open that step; a number lights up only for a step you have finished. iPad gives every button a bigger touch target; Computer draws a denser picture. Help changes the help around the task, never the task itself. Fill screen hides everything but the tool.
