This sounds super cool for aesthetics!
I'd like to see more possible options, perhaps even for other planets. An option to make it non-permanent and vary like real life, with different intensities, and including thunder and lightning strikes (non gameplay functionally, just visuals.)
Maybe even snowfall? Hail? Wind? Dust? etc. Would be very cool if snow could build up on Nauvis, but without the gameplay aspect from Aquilo.
Could also be local to different biomes.
I don't know how much is possible to do with the current API, but hopefully some of it is!
