Features

uYou: uYou has a ton of features that I can't list them all. Visit here for more info!
iSponsorBlock: Skips annoying sponsor ads inside videos. iSponsorBlock is based on SponsorBlock engine. Basically, this is the iOS version of the SponsorBlock extension.
YouPiP: enable YouTube's native PiP. More options are in YouTube Settings => General.
YTUHD: unlock VP9 codec and in effect, enables video quality of 2K and 4K. You can enable/disable YTUHD in YouTube Settings => Video quality preferences.

And more...!

YTClassicVideoQuality: since YouTube v16.xx, you need one more step to change the video quality. YTClassicVideoQuality brings back the old video quality selector, which is a lot better than the new one.
YTNoHoverCards: offer an option to enable/disable the annoying suggested videos show up at the end of the videos.
YTSystemAppearance: sync the YouTube theme (dark/light) with the system theme.
YTNoCheckLocalNetwork: block the Local Network permission popup.
YouRememberCaption: make YouTube remember your video caption setting (if not already).
