UQueue is a browser extension written using the chrome API. It is a YouTube add on used for watching multiple Youtube videos painlessly. Currently it supports disposable and editable queues, skip buttons and an option to force an embedded fullscreen player.
There are no dependencies other than an up to date chrome browser, everything is native HTML/CSS and JavaScript.
To install the app yourself navigate to chrome://extensions/ and click enable developer mode in the top right of your screen. You should see the load unpacked option appear. Click it and point it to where you placed the app's folder.
