Pomodoro clock extension by macmorning

Use this extension to organize your work in short streaks: work X minutes, have an Y minutes break, and so on. You can configure the duration of each streak as it suits your own pace. The extension will display a notification and play a short ring at the end of each timer.

For more informations, read this article on wikipedia about this time management technique.

The source code is available on Github, not minified and not obfuscated in anyway. Post your bugs and enhancement requests there, even though I'd like to keep it as small and functional as possible. All comments are welcome. :)
