I started using the Pomodoro Technique about a year or so ago and though Idon't religiously follow the process in anyway or form what I have taken from it is the need to simply shut everything down andwork on a single task sometimes. For those of you who don't know the Pomodoro Technique is a way to manage your time in to sizable25 minute chunks (with 5 minute breaks) where you focus solely on the task at hand. If my high level breakdown hasn't done a goodjob of what the process can do for you don't worry, you can check out the site andeven download the book for free to find out more.
When you start using the process though the one object you need is a good timer which fits in with your work flow, enterChromoDoro. The Chrome browser is one program I have open all day for emails, reader, twitter etc so having a timer that works from the browsersimply fits straight in with my current development setup. After installation it sits in the top bar and once set displays a countdown timer in minutes.
There is not much else that can be said on ChromoDoro except the current version is 1.4.0 and though not bursting with features it doesn't have to be as it does its one job really well.
