Oleg;
I'm hoping my title says "thank you" (I used an online translator).
Disregard the negative jerks like Redwan and Seeker. They'll never be satisfied and are probably console gamers anyway (sarcasm intended LOL).
The FMB looks great, lots of options. Yes it may take some time to learn how to use it but that's the price for having a great game like this. I love the IL2 FMB and it looks like you've added so much more to this next iteration of flight sim.
I won't ask the standard "what about X? Can you change Y?" It's a bit late in the process to be still asking for this type of stuff.
I'm sure you know from experience you will never please everybody but you will definitely please enough!
All the best.
