I like the Tomato Clock the way it is and wouldn't change a thing. The small tomato icon showing the remaining minutes is unobtrusive and a great way to see where you are on the clock; click on it and you easily get to the full control panel. The stats page is spectacular, allowing you to see daily, weekly and monthly progress. The Tomato Clock is the perfect tool for people who follow the Pomodoro Technique. My understanding of that philosophy is that you challenge yourself to achieve certain uninterrupted sprints of focused work, and therefore each tomato to be earned is indivisible. If you can't work the 25 minutes straight, then you haven't earned the tomato and you must reset the clock and try again. The goal is that you train yourself to focus on a particular task for a set period of time, after which you can unwind for a brief period (say 5 minutes) before getting to another focused session. Once you have achieved a certain set of tomatoes, then you can take a longer break. By setting a goal of earning so many tomatoes in a day, you may find that you can get much more done in fewer hours than you had been able to do in a very long, undisciplined stretch without the system. By employing a strategic balance of work and breaks, the technique can help you become more efficient and productive without getting fatigued. A "pause" button seems antithetical to this approach because it interrupts the flow, so if you add one I would keep it hidden deep in the options page for users who really want it so that it's not so tempting to others to push.
