Clouds shadows would be interesting, 'cause it brings more immersion, as we dont have rain, it still makes the day darker.
Now, when we set full clouds, its still bright and the sun dont get affected by clouds!
I am not a programmer, nor know anything about modeling, but maybe theres a way to just make them "solid" but we could still pass through them, so it would have shadow.
I dont know if its hard to do that, but probably easier than adding a new clouds rendering model.

Have a nice day
