nice, mikhayl!
the quick chart seems to be a good feature, i will give it a try on weekend. the manuall recognition was a thing i didnt like, because this method was too slow and on long ranges not realistic (targets couldnt identified on 8 km, i think). the only thin g you can do is estimate the targets mast. with your quick chart, some common mast heights are shown in a fast way, thats nice
