Similar to the the contact editing dialog, but designed to allow contacts to be edited quickly.

This extension shows you a list of available address book resources. You can check/uncheck them to show/hide the entries of a specific address book.

It is also possible to Add, Edit or Remove an resource, for more information about this see how to configure resources.

This extension provides easy management of email distribution lists: just create a new list and select a contact in the view; then, after clicking Add contact, the selected contact is part of the distribution list. A simpler way is to drag a contact from the view and drop it over the distribution list manager. See Settings Menu about how to add an extension.
