First and foremost, love it, more please! Right, onto some actual feedback.
First off, a minor glitch noticed in the Sleek Creek Khajiit house, when it's raining and you go inside the house, the effect lingers, making it look as though you have a VERY leaky roof.
Secondly, housing would feel so much better and more customisable for role play purposes if the player was allowed to interact with the skybox settings in the House Edit settings menu. Being able to freeze the skybox at a particular time or to make it accurately follow a real world time frame as well as choosing what the weather should be would be ideal for role play.
Third, when purchased with furnishings there doesn't seem to be any kind of sleeping area in the House of the Silent Magnifico.
Right, that's all my feedback for the moment, keep up the good work with housing, Zeni!
