Fantastic feature set! And the means for entering equations is excellent.
I agree with others that it needs an instant calculation option. Suggest that there is such a setting where the result of the calculation is shown iteratively while writing a script. At each press of Return, show the result. With this option disabled the app would behave as it currently does.
This should be simple to implement and would make the app complete.
Would also like the ABC keyboard to hide and return to the calc keyboard when pressing Return.
