I’m not sure if this is already a feature request or not. I looked hard before posting this though. But, another thing that would make IF more realistic is adding more weather features. Like clouds, and stuff like that. IF is the most advanced, and life-like flight simulator I have ever seen for mobile. But, even the less-advanced sims I have seen have weather features.
There’s already a topic for cloud layers
As well as rain what else :)
Search and you shall find.
