Hi again. Added a service worker to the nightcore maker. That means you can use the app when you do not have internet, in the browser. There's one catch though; you must have visited the site once before in a supported browser for it to work. You can see the service worker support here http://caniuse.com/#feat=serviceworkers
, green ones are supported.
So if you are on the latest Chrome/Firefox/Opera and visit the app today, you can unplug your internet, and still use the app! :D
