Nextube - The missing next button

Nextube adds a YouTube next button in your browser windows!

No more searching for the YouTube tab just to change the current song,
with Nextube, just press the next icon and YouTube will play the next available song.

Notes:
- Please refresh your YouTube tabs after installing Nextube
- Nextube will only control the first playing YouTube tab so you can safely keep other YouTube tabs/windows open when not playing.
