Tbh the camera can travel to show the skybox when characters prepare to go to sleep and suddenly you're problem is addressed and everyone is happy lol.
No, but really I'm totally against it ^^ It's just more clicks. More. And More. If there is no balance around sleep and on highest difficulties Larian admits I can sleep for every encounter so they will just gatling gun my face with magic missiles AND I will have to take care of fluffy pijamas I will eat my keyboard :P
