Nice - a few features would turn it into something great.

This is a very nice graphical calculator. But here are some suggestions:
Make it possible to resize the axis independably. Now i have to work with factors to fit it on the screen.
Make it possible to show only relevant part of the function (e.g. 0.125 < x < 1).
Make it native on iPad.

The first two are very important features, the latter would be nice.
