As an Ace Combat player, I've found that incorporating roll direction allows for a wider range of maneuvers beyond simply turning left or right, much like driving a car. While adding roll direction requires significant effort, it enhances gameplay by making biplanes distinct vehicles and offering a more diverse gaming experience.

I understand you, but I decided on a 2-axis movement in favor of easier vehicle movements; after all, it's Minecraft and not a simulator :)
There was a pull request going on somewhere, but I lost track of it.

Ah here it is: #196

And, providing an option to switch between the traditional mode and the roll direction enabled pro mode.
