• 20 Cubed Reminds You To Take A Break

    Chrome: We’ve discussed the 20-20-20 Rule before, where every 20 minutes you take a 20 second break and look at an object 20 feet away to relieve eyestrain and rest your eyes. The 20 Cubed add-on for Chrome will automatically remind you to take those breaks so you don’t have to set your own timer.
