Region View Modes

"A surprisingly simple, flexible layout solution made possible by placing fields in regions. Region View Modes is just a bit of glue to join Drupal's theme regions and View Modes."

Override Node Options

This module "allows permissions to be set to each field within the Authoring information and Publishing options field sets on the node form. It also allows selected field sets to be set as collapsed and / or collapsible."

Jammer

The Jammer module hides particular elements from edit forms, similar to the Simplify module. This module is mentioned on the revisioning module/s project page on Drupal.org.

Node changes

Used on http://drupal.org, "This module stores the changes of a node into a field attached to comments allowing to display a kind-of activity stream on the node much like on drupal.org issues just with a lot less custom code."

Workflow

"The workflow module allows the creation and assignment of arbitrary workflows to Drupal node types. Workflows are made up of workflow states. For example, a workflow with the states Draft, Review, and Published could be assigned to the Story node type."
