Tweaked version ? by Majd Alfhaily --
Cercube 4 is the best all-in-one video download extension for the YouTube app.
The official YouTube app is a great client but it lacks several key features that most YouTube users want like video downloads, customizable playback quality, no video ads and much more.
Cercube 3 takes care of the missing features in the app. It?s built right into the YouTube app and adds these great features:
Download any video in any available quality. (from 144p to 1080p).
View, manage and share all your downloads in Cercube?s download manager.
Block all promoted cells and video ads.
Send downloaded videos via AirDrop to other devices.
Background playback capability for both streamed and downloaded videos.
Downloaded videos are displayed within a beautifully crafted downloads manager that shows all the available information.
Select which page to display when launching the YouTube app.
Unique short-hold button gestures.
HD streaming on mobile networks.
Auto replay videos.
Trim tabs bar.
Hide floating upload button.
Hide ?Trending? tab.
Add backward & forward rewind buttons to video overlay.
Cercube options are configurable from within YouTube settings.
