Thank you very much for explanation, Yegor. Its a little bit more clear now for me. Sometimes its strange with us, who doesn't work with code and doesn't know how the things are related in between. Therefore some questions could be without sense.Thanks to both, Yegor and George, for your effort and please keep working on it if, you'll have time for it.Btw. sorry if this was explained somewhere, but from pure interest, why is there such a big size difference between the two wrappers, or better to ask why is george's wrapper so much bigger?
