The best YT client but needs some UI improvements

Ive tried almost all YouTube clients on the app store and this one is by far the most polished. The app is beautiful and fast. It also supports all new iOS 9 features like picture in picture and split screen on iPad. My favorite feature is that you can pin playlists to the side bar so you dont have to search for them every time. I also like how you can precisely adjust playback speed - i save a lot of time by watching most videos at 1.5-2x speed :)
I really like how the app looks and feels but still there are some things that could be improved:
-the quality selection button is not available in full screen and is too small. I use it to change playback speed and miss it too often.
-it would be great if there was support for 60fps videos. Dont know if this can be done though, as far as i know only the official YT app has this feature.
-There are too many hexagonal icons. Especially in the sidebar and below the video. I get the idea but they are too distracting and the app would look much cleaner and better without them.
Other than that its a great app and the best YT client ive seen on iOS. It totally worth the price.
