Multiple windows on the screen are wonderful when you want to multi-task. But they can quickly become a distraction. That’s where Think (Mac only) comes in. This clever little program covers all of your open windows and desktop with a blank, colored backdrop. You then choose one application you want to “illuminate.” That application stays above the backdrop and creates a distraction-free environment for you to get some actual work done. This is a must-have program for writers. Best of all, it’s free!
