If you're a night owl like me but don't want to change your Chrome theme to something dark, you might like this app. It lets you instantly open a tab which is completely black so you can keep Chrome open at night without, you know, going blind. What else can you use "Black" for? - To black out a screen for more comfortable movie viewing (T0m-S). - As a mirror (if you have a glossy screen) (anon). Let me know in the comments below if you discover an innovative new use for this app! I'll include it here. Want a "blacken screen" Chrome extension?
