Speaking as a non-phone player, one feature i would like to see is,
As soon as the game turns into a race, enable greedy bearoffs, or at least ask the user if they want to enable greedy bearoffs.
I don't mind waiting a bit pretending that my opponent is thinking about what to do with his opening 6-1, but when bearing off a 5-3, i keep thinking about the poor guy (no gender neutral anonymous noun in english) fat fingering dragging the 5 to the bar, oops that was a 4 undo drag a 5 to the bar...
