Make it so that there is a button where you can make the Attitude Indicator and Gauges old or new. Also, there is a glitch where sometimes when you select a part with settings, it doesn't show the settings at all. Maybe fix that? Also, when you crash, the cockpit just ejecting and goes flying. Fix that as well. Also, make a airliner throttle like the ones on Boeing planes, using levers for throttle is so unrealistic. Not a demand, just some suggestions.
I'm honestly happy with the Attitude gauge. They don't really have any use on Modern Aircrafts, because the Ball Attitude Indicator is what is commonly used.
The glitch is pretty annoying, and I don't experience it in other parts other than the Fuselage type blocks. Pretty annoying, but pretty easy to fix. Just point your cursor to another fuselage block, and then point back to where the bug happen.
While I slightly disagree with this (since you could just make a custom throttle stick using a joystick base, fuselage block, and grabable part), it could be a bit more convenient.
Thanks!
Or, just create more variations for the lever, like a lever with a ball knob or allow another attachment to the lever. As for now, use the grip and control base instead. I like your idea though.
