1. Smooth animated flaps
2. Visualize airbrakes
3. Visualize jet engine reverse thrust

Number 3 is already a thing. There's already a rotationVariable for it. As to number 2, I'm going to lump reverse thrust into airbrakes, as having yet another keybind would make the joystick GUI overflow and doesn't add too much to aircraft systems. Basically, if players want to have airbrakes on their planes, they should be linked to reverse thrust as actual airbraking won't be implemented due to the complexity.

And as to smooth flaps, that's do-able for sure. Will be restricting this ticket to that item.

Addressed in V14.2.0.
