Frustrating for toddler!

Good app, but could definitely use many improvements! When tracing letters, toddler gets frustrated because if he accidentally touches the screen in 2 places, a long long appears across the screen ruining the appearance of the letter. Another problem is that he frequently presses the "home" button by accident which exists the letter tracing screen and forces him to start again from the beginning. There should be a slider or something of the sort to remedy this. It would also be great if there was an option to take a picture at the end of the letter tracing game so that parents could keep track and point out improvements to toddler.
