What does the app use to determine whether or not to show just 5 buttons at a time, or all 15 buttons when viewing a 15 button keypad?
Because I'd like to have a way to force it to show all 15 when using an android tablet in landscape mode. I can understand how it would be problematic on a phone in portrait mode. But in landscape mode there's more than enough room to show all 3 sets of the buttons.
