[Feature Suggestion] Void view

[MineAndDine96]

I would suggest an overlay, that highlights the y=0 mark in your world in a certain area around the player. This would be very useful especially (and basically only) when building or flying in the end somewhere in the void and would make it harder to loose the orientation and fall to your death. With just this overlay you would know where the bottom of the world is better and wouldnt loose orientation so easily.
