I'm a big fan of HKN too. I started with a different software solution, finally got fed up with a lack of attention from the author, tried HKN mostly just to kill some time one evening, and was converted by the end of the session. It is a mighty thing! I actually enjoy delving into the guts of HKN (I guess the nearest equivalent would be deriving enjoyment from installing Windows or configuring a router. So I'm weird, so what?), but am sure I'll forgive the new program for making that unnecessary.
