The sleeping details chart that was just replaced this year was much more user friendly & I prefer it because I could see the precise times I was in which sleep stage. I used it daily & could compare my known awake times when they happened to recognize what may have contributed to waking. And just seeing the nightly patterns at all hours was very revealing. I beg of you to go back to the more detailed chart. I also like the coloring with black background. I know there's a lot of your users who are unhappy with the changes as well. That chart was one of my favorite parts of the fitbit format.
