Aesthetically Pleasing Updates - Make The World Feel More Alive!

I think it would be neat to have a few added updates that are mainly to make the world feel more alive. Granted we are the only player, but the world of minecraft as a whole is still pretty vast and pretty lively.

Adding updates that are more so aesthetically or graphically pleasing can go a long way.

Maybe the ability to see wind blowing at times, or fireflies over a lake or in a forest, without being food for frogs ;). Updates like these, despite not having a block based use, can still have a very significant effect on the playerbase
