This is a simple suggestion that, no doubt, will be an incredible mess to actually make work... or at least so I suspect, given what I've heard of the game's original source-code being essentially spaghetti.
In essence, I was hoping there would be a way to let the players permanently set what pose they use to fly. Something that goes into effect every time they go into a "flying" animation rather than having to mess-around with macros that only work while auto-running.
EDIT: Flypose also doesn't seem to work with Afterburner at all.
