I would love in-cockpit wind noise that changes with speed ... not sure it's possible with such an old engine and you have worked miracles already - but the sound of rushing wind would knock the immersion out of the park!
I would love this too, if it's possible.
I have something that I "think" might be an easy add. I fly on Easy Outcome setting because I don't always agree that if I land lightly wounded at my airfield, it sometimes marks me Dead anyway when on Normal outcomes. But I would like a button added, if possible, that allows me to mark myself dead, maybe add an "Are you sure?" pop up. That way, I could fly on Easy outcome mode, however if I get shot down, crash land hard or literally killed in the air, I can mark myself dead at the end of the mission.
