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."

Block Reference

"Defines a field type Block reference which allows the block to be displayed as the content of the field." Alternately, if the bean module is enabled, blocks can be referenced using the entity reference module instead.

Field group

"Fieldgroup will, as the name implies, group fields together. All fieldable entities will have the possibility to add groups to wrap their fields together. Fieldgroup comes with default HTML wrappers like vertical tabs, horizontal tabs, accordions, fieldsets or div wrappers."

Views Autocomplete Filters

Get autocomplete working for views exposed filters. From the project page: Add autocomplete functionality to the views filter text fields. It works for node titles or cck text fields. The autocomplete results are actually the view results, so they are view related. How to use it: (New) Video Tutorial : http://codekarate.com/daily-dose-of-drupal/drupal-7-views-autocomplete-filter

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."
