Since this project was half an attempt to solve a problem, half a learning experience for getting grip on how to use PyQt, the current ui-code is quite messy and the structure is far from optimal. Everything is one single .py file...

Moreover, I have stumbled upon quite a lot of bugs and strange behavior related to parameter sets that are difficult to solve in a nice way.

Therefore the next step is to structure the code a bit better and to do some changes in the parameter-concept, which hopefully would make further development more joyful.
