Little confusion but best one I ever found

So I got on and all the settings were great, but the only problem was what did all of the buttons do like the color button wouldnt work I gave this a 4 star because I could just slide up and use that its like the same thing, and because it was the SMALLEST bit confusing but this is the best book app Ive ever seen
