THE WIZARD DK: for me personally the issue with suggesting things in these progress threads are: there is already forum for suggestions, the suggestion was highly likely already posted there (as there was being posted pretty much everything possible in this universe or at least it feels so to me), Scawen is (now I'm guessing, but I'm also SW developer, so I may be not completely off) mostly interested about feedback about things being presented in these threads.
I have no strict rules at what point a subtle nudge turns into "this is too much", as I guess some suggestions directly related to the work presented are actual feedback (and mostly constructive one), but I think at this stage when Scawen is just wetting his fingers with shader/PBR rendering, bringing topic of atmosphere simulation, is kinda distracting.
I would strongly prefer if they managed to finish at least this new shader revamp of all maps, release the patch, and then check on these new options... then again the nigh/day simulation is also unplanned, but did fit very well with the rework of light/shadow engine rewrite.
So in the end the only authority to decide what is too much is Scawen, and I'm pretty sure he likes even too far fetched suggestions more than silence, so you are probably right about posting those. But bear with us, who can get mildly annoyed and worried about possible consequences of such distractions, I really hope we will not have to wait till 2023 for this patch being released.
