Main menu layout changed.
Back button now shows "main" instead of "main menu."
"Pick Background Color" now under Settings.
"About Us" not "Contact Us."
Text size for "Blue" now same as for "Magenta."
Renamed app to "Perfect Potty Pal." (Note: this gets truncated on the Home screen, due to length. "Potty Trainer" fits. "Potty Trainer B" doesn't fit. So about 12–14 chars fit, including spaces.)
