A module that hides some things for the user. For example, you always get a complete explanation of a text field which html can be used and which can not. Disturbing ... With Simplify you can hide this and other things.

So it is normal:

Field Permissions

In Drupal you can set permissions on content types.

With this module you can set permissions for every field. So it is possible to hide some fields unless the user is logged in. You can also give permissions to create or edit content.

Workbench moderation

Content can be maintained by a team. Permissions can be set by role. You can give access to somebody to produce a draft version of new content, without producing it. It needs a review of a publisher. The Workbench module (not this one) gives a view display of all the changes that have been made.
