Love this app !

Does practically everything you could possibly want with surprising ease, from simple calculations to more esoteric calculations. Absolutely essential for immediately checking out those problems that have been bothering you for weeks, but that the sudden flash of inspiration hits you when your out buying milk or something.

Two suggestions :
1) Add a "Contact Us" option to report problems or make suggestions.
2) Move or duplicate the Mode button from the equations screen to the graph screen and allow the displaying of formulae in more than the native projection.
