I can't remember if I posted or not on the suggestion thread, but I always though it'd be neat if they could link up some windows to a skybox. Maybe one with some torn flailing curtains with a storm outside, or a nice sunny day with some birds flying around. It'd probably have to be limited to the base walls to work, possibly event replacing the current windows. Kind of a dream house feature and not likely one within the scope of this game's dev team.
