I hacked in a spectator-like follow mode

Is this kind of thing something that you'd consider to merge? I'd be willing to put in some work to make it nicer, this is just a simple hack that works for me:tm:

I like what's been done here, thank you!

I agree with what @MattSturgeon has said. I think the two keybinds should be replaced with the default pick block bind. I think it feels more intuitive and it uses less space in the controls menu. followEnabled definitely needs to be checked by isEnabled, too. The other style-related changes would also be appreciated.
