That sounds like a very useful mod for players who use headtracking devices like TrackIR or Tobii. Being able to toggle the head or eye tracking on and off without leaving the game or going into the settings can definitely enhance the gameplay experience, especially for those who switch between different control methods frequently.
Having the ability to customize the key binding for toggling head or eye tracking is also a great feature, as it allows players to set up the controls according to their preferences.
It's important to note that for the mod to work, headtracking must be enabled in the game settings. This ensures that the mod can interact with the headtracking feature and provide the toggling functionality seamlessly.
Overall, this mod seems like a practical and convenient addition for players looking to have more control over their headtracking experience in the game. It offers a straightforward solution for managing different camera control methods while in a vehicle.
