If you don't have the time to download and setup the newly released Alfresco Share 3.3 Community version, here's a video that previews one of the new features in that release: Data Lists.
Transcript for the video can be downloaded here.
A high resolution version of this demonstration can be seen here.
The Alfresco 3.3 Community release can be downloaded here.
The video doesn't get into how the lists are defined using the Alfresco Content model. It's possible to create new Data List types or to modify the columns of the existing To Do List.
The To-Do List example that ships with Alfresco Share is shown in the video and the content model definition can be found in a file in the Alfresco war under models called datalistModel.xml.
