screenlog.js 
Bring console.log, on the screen
Ever faced a situation where you said "Why doesn't this bug show up when developer console is open!!"? And since the bug doesn't show when you have console open, you cannot do debug logging using console.log.
Enter screenlog.js. screenlog.js brings the developer console right on your screen so that you can do logging without having the developer console open always.
Example
Usage
Do npm install screenlog or bower install screenlog or download the project.
Drop dist/screenlog.min.js into your web application and initialize it with:
screenLog.init();
And you are done!
By default, every next console.log (or info, warn and error) in your app now starts logging on the screen as well as the console. Or you can use screenLog.log() instead to just log on the screen.
Public API
