It is wayyyy overdue, but my time has been fleeting as of late. I have release Imagine v2 out onto the Moodle universe and it comes ready for 1.8
The design is set so that the homepage is fixed width to allow for some more creative design options and the course pages are 100% width to get the most out of the real estate space.
It comes with all the css needed to use the accordian format and I have updated the icons to cover the newly needed images for 1.8 as well.
Enjoy. Please make sure you check out the readme before posting.
You can see it in action at the following URLs:
