Page Transition

hi and good work on this one!

i just wanted to mention i had to change the jquery.animsition.js files for the newer version to fix the back-button-blank-page bug. I think it could already come with the plugin download...
Oh, and also the transition works on everything in the page except the parallax image header... (adamrom-parallax-scroll)

cheers :)

great but...
