It would be nice to have more options with the sky's. I'd like to change the sky on my cottage to night fall, with rain. And I would like to change my winter castle to night sky with snow fall. If the rain or snow isn't possible, just being able to pick if we want daytime, nighttime, dusk or sunrise would be awesome.
Picking times of day would be nice, also if we could apply a sky box to the inside that would be great. Many of the houses are just black inside. More generally it would be cool if we could control the lighting in houses with castle magic or something.
