Some of you are aware of the fact I have already prepared two chemical calculators (see signature). I am planning to extend the line of programs and I have several ideas about what could the next calculator do. However, before starting work I decided to do a quick poll:

What type of calculations would you like to have automated?

Which calculations are the most tedious?

Which calculations are eating most of your time, regardless of the fact that you know how to do them?

heat of reaction? if u can find a standard enthalphy change for some common bonds that is.

how about a calculator that allows you to interpolate data from tables.

example: steam
1. specify the pressure and the program returns the saturation temperature, enthalpy and entropy
2. specify any of the two: temperature, pressure, enthalpy, entropy, and the program returns the other two values and also state the state of the steam
3. may return other data such as specific volume, density, etc

it would be nice if the calculator supports steam, ammonia, air, co2, n2 and other common refrigerants.
