I’m far too busy doing my day job at the minute to give this a proper right-up, but it’s worth noting the release of Facade, which is a home-screen plugin allowing..
Launcher bar – Bring your favorite application shortcuts directly to your Home screen.
Tabbed interface – Ability to put all Facade sections inside a tab interface or outside.
Calendar – View a list of your upcoming appointments for the next 30 days.
Tasks – View your tasks grouped by progress and completion state.
..all on your home-screen.

Or, if you want to download it then you can get the very latest version here.
Facade is in its Beta stage at the moment and you can post comments in their forums.
