Basically what powdersim is all about is we are going the other way of TPT. We are implementing things into powdersim that wouldnt be even thought of in TPT. We are also using other languages besides C++/C.
Not only that, I personally have been working very long hours and have no time to help with development of new elements in the mod. I am sure that @me4502 is busy as well. It is going to take a very long time to get powdersim to the point where we want it. And we are in no rush to get it out with a crapload of bugs. When we have the time, we will be working on adding new things and getting it to the point of where we want it. Until then, you will have to be patient.
