"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."

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."

"The Custom Contextual Links module allows you to add your own links to the contextual drop down widgets of blocks and nodes."

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.
