Floating Popup Tube Player is a free and very handy app for watching Youtube videos and YouTube playlist in a pop-up, floating window on the side of the screen. This way you can have your Youtube videos always in front of you, while you are working or doing something else, and you won't need to keep opening the Youtube app to play your playlist or videos.

To get started with this app, simply open the app, play your favorite video, or select one from your playlist. If you want to watch your Youtube videos or playlists in the background, simply set the video to repeat every time you open the app, or shuffle the playlist.

Once you start the video, you can pause it or stop it by tapping the screen. You can also use the volume button to increase or decrease the volume of the audio.

To get the latest updates and the app's description, simply tap the Settings button and go to the Developer option.
