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."

Bundle copy

Bundle Copy is in Drupal 8 Core CMI. It is a replacement for the Content copy module which lives in the CCK project for Drupal 6.

Field Conditional States

With the Field Conditional State module you can change the state of any supported fields form element depending on the content of other fields. This is done by providing an UI for Drupal's States API. All the changes made to a form by FCS (Field Conditional States) utilize only the States API and therefore are clientside only.

Field formatter settings

This is a great API that many other modules use. Here is the info from the project page that summarizes it well: "The Field API in Drupal core lacks the ability for other modules to easily alter field formatter settings forms and the formatter summaries. This module is a small API provider for other modules since it's too late to get the hooks into core..."

Edit profile

The description at Drupal.org describes this module the best:"This module creates separate "Edit account" and "Edit profile" tabs for each user, with custom user fields configured under "Edit profile."
