I agree with missing a fuction to save the FMC Flight config ... but I disagree with the second part. I am a software product manager myself and saving and reading some xml data from a file does not cost even half a day of coding. Though I know that devlopers are driven by impossible deadlines and idiot sales people thinking in terms of profit quarters rather than acting in the best interest of the buyer. Absolutely annoying every time fsim decides to crash or you decide to quit for the day you need to reconfigure the same route. I would'nt have mind paying a couple of bucks more for that feature it could have speared me endless hours of frustrating re-configuration. Also the handbooks and tutorials are stuffed with information they are missing the essential red line for people to follow to get started. For the rest very nice work keep it up.
