Gonna use this thread to shout out https://github.com/YTLitePlus/YTLitePlus There more than enough options for android users out there, this one is for iOS though. Tried it out this weekend on my jailbroken iPhone 6. If i read it correctly it should also be installable without a jailbreak but not that easily. Its super cool and sadly feels so weird that you got the option to do such shocking things like disabling shorts or hide certain buttons, its really fun.
