There are quite a few really cool new features mentioned in the Sneak Peek documents. It would really help to have an example account where all of these new features are imiplemented.

For example:

New Portlet Types
Three additional Portlet types, namely FORM, LIST, and HTML are available with Version 2007.0. The FORM Portlet allows you to provide a basic form with up to one submit button on a Dashboard Portlet. The LIST Portlet can be used to create a custom list consisting of user defined columns to display any data, including search results, from various record types. For example, you can create a custom list of contacts and customers using multiple searches. The HTML Portlet provides an extremely flexible presentation format to display custom HTML content including images and Flash, directly on your Dashboard.
