VR: Need to be able to disable strafing and turn 90 degrees at a time

I've been getting super nauseous from Minecraft in VR because I keep lazily strafing left and right, and turning with the right joystick instead of turning my body. This is the first time I've gotten nauseous from a VR game since the early Rift DK2 days, since I've been really smart about bailing out as soon as something starts to go wrong, but Minecraft is so much fun that I keep forgetting to sign out until it's too late, haha.

It would be tremendously helpful if I could optionally turn off left and right strafing, and I could set the right-stick turning to go 90 degrees at a time. I think between that and the other adaptations to help with VR comfort, I should be totally fine.

Thanks in advance,
Ray
