I appreciate you making and maintaining the mod. I have a small suggestion to add to camera mod. While in 'FreeCamerPlayerMovement' could you add a small screen for player perspective. I edited a photo to give you an idea.

If possible, some way to get sound from player's position too. Something that can be toogled

oh ye that would just be a reword of the cameras pos for the SoundSystem and for PiP it would be a bit of work cause you would need to make it a separate Camera Renderer. It would be Doable but Might not Be worth and in any way it would not come to 1.14+ for a while as to not bother masa again with more stuff stopping his beloved rewrites to malilib
