This project is now dead. You can achieve what I was trying to accomplish in the built-in Chrome JavaScript Console by simply holding down shift while you hit enter. This effectively kills this project as the purpose of this extension was to allow multi-line in-browser prototyping of JavaScript within any web-page from within Google Chrome the way you can in Firefox with Firebug.

If, for some reason, someone wants to continue developing this project, leave a comment and I will link to you. Have fun :)
