I vote more of these. Very useful!
You're a legend, Chris. Thanks for taking the time to walk through the S3 configurations while explaining them well -- it is can become pretty daunting by yourself. Cheers.
Chris, this is such a game-changer for me. I am actually looking forward to my next jquery feature to implement this... rather than dreading it like usual. As you describe, it puts you in the same headspace as you are in while doing normal rails model work.
Great stuff, mate!
