I kind of hate the rating systems on beds...

This is going to sound like a tangent, but... in previous iterations of the game, when the sim went to bed, you could see a little timer if you hovered over the sleep bar that indicated when (the hour and minute) they would wake up on their own/if you let the sleep bar fill all the way. The reason I bring this up is that now we don't have that feature anymore, it makes it even harder to guess when to send them to bed, particularly with the sleep ratings all over the place. I'd like to see two things at the same time: a return to the sleep time indicator, and as other people have suggested, the ability to improve/customize the bed settings with handiness.
