I have a problem with `TabLayout`and `AppBarLayout`, because I want my tabs to be at the bottom and right now they are at the top, they hide with the image as I scroll up. And there's the second problem - `AppBarLayout` with image doesn't hide as I scroll the text, it only hides/shows as I try to `scroll` image at the top
