It would be great to add fog more settings without tweaking into the code along with global light source.
What I mean is that for fog we should be able to change its density and distance, for now we can only change color.
And make it available as a separate biome element because it's only available in the dimension element.
And within that also add, if possible, more customization upon global light source. When enabled everything is pitch black, so we should be able change its strength.
That's my suggestions. Keep up the great work I love it so far!!!!
