Hi and first of all thank you. I love your plugin.
I needed an HTML5 placeholder for the forms on a current project and found this great forum thread that fixed my problem:
I just threw a gist on github with both the text and textarea file in /modules/ fixed: https://gist.github.com/2901669
I hope this change makes it to the final version, would be a shame to fork this plugin just for this minor thing.
