WordPress plugin Design needed [PSD, CSS]

We need a design for a 'comments plugin' that will be used on WordPress. Right now we are building this plugin, adding new options and features but we also need a graphic design that will organize and structure the comments. You can see the plugin in action on this page: [login to view URL] The comments plugin is the one floating on the right side. A user can drag and drop an item on any sentence, write a comment and publish it. Feel free to experiment with it. To view the new comments inline click on the small plus "+" signs. What we need is a design that would be attractive (web2.0-ish), intuitive and that will also keep thinks organized (i.e. the main content, the sentences and the comments - all these elements have to keep their structure and also to interconnect in a very intuitive and attractive way). We like simple, clean design. You can draw inspiration from the [login to view URL] system. We need the PSD and after approval we also need the design to be implemented.
