When editing a node, how do I keep additional fields minimized

What I am trying to do is to minimize all the fields are appear when editing a node. To be more clear, when editing a node, I have several fields beneath the content (such as Input Format, Revision Information, etc...), and I want all of them to be minimized by default.

How can this be done? I am roughly familiar with the Drupal API, so dont be afraid to talk about hooks, or custom modules if need be.

Thanks,
Steve

EDIT: Solved this myself by using hook_form_alter() and changing each fields form to be closed by default. Although vertical tabs is nice, it grabs some things which I dont want to be part of the menu (like taxonomy for example)
