Finally got to test it... I made black box testing (no debug info activated, especially considering the fact that it is very CPU intensive). Everything looks very good, I am very satisfied! Even Abort button works like a charm! The only 2 things to note - Presets range is way too big; # of Samples can be only 16/32/64/128, but there is possibility to choose in between them. They are not critical, just to mention In any case you rock!
