This is the ever-shrinking list of things the current version of Kalkulator does not do.

• Calculations on complex numbers
• Symbolic algebra (no way!)
• Financial arithmetics (compound interest, payoffs, etc.)
• Programmability (loops, branching)
• Plotting of two-, three- and n-dimensional surfaces
• Bessel functions, elliptic integrals
• Anybody's homework

Some of the points above are planned for implementation in the upcoming releases; some never will be. If you have strong feelings about some features, drop me a line. I read all my mail and answer most of it.
