My thanks to the folks behind Coherence X4 for sponsoring the site this week. Coherence X4 allows you to turn any website into a chromium-powered app on your Mac. Simply pick a site, enter a name, and pick an icon, and Coherence will turn the app into an isolated application separate from your main browser. Readers get 20% off this week when you purchase Coherence X4 or when you use the promo code 512Pixels at checkout.
