thank you very much, I do appreciate you taking your time to implement that feature; you would be surprised how many people find it 'too much of a hassle', thus limiting their audience, based on their own personal preference of control-scheme - something which hasn't occurred until recently, which is a crying shame, since (to my knowledge) there's a lot of us old gamers out there who do prefer inverted (due to growing up with early flight-sims, etc.)
once again, I appreciate you taking the extra time, going the extra mile
