EuroOffice Take A Break
Continuously staring at the computer can cause headaches, blurred vision, neck pain, fatigue, dry eyes. EuroOffice Take A Break extension tries to help you avoid or reduce these problems. It reminds you when to take a break while you are working with OpenOffice.org.
A little icon on the status bar will be flashing every 15 minutes to remind you a short break. You should sit back and close your eyes, or look outside the window for a while.
A pop-up dialog will remind you a big break every hour. You should stand up, get a cup of coffee, do some stretching, or go freshen up.
You can adjust the timers according to your own needs.
Note: EuroOffice Take A Break is an extension that was created by porting a popular Firefox add-on (Take A Break by Zen).
