Ken,
The Clarizen homepage provides you with a single page view of all work items, cases and conversations, giving you an easy to read and easy to access overview of everything that needs to be done today. It is only the first release of the home page and we are going to allow much more configuration of the panels and the quick actions in a future release. Currently, the ability to add a custom panel to show a calendar and Task emails is not available.
Sincerely,
Boris
