Address book for Privatemsg available?

I built something like this using Flag and Views. I allowed users to flag people they want to save to their contact lists. Then I made a view showing the flagged users and added Privatemsg links. Feel free to re-open if you need more details.

@ptmkenny: Would share your code as a feature?

Greetings,

Sorry, I can't export the code easily as a feature, because some parts (the link to the contact list on the profile, which I display using Views and Panels) are unique to my site and it would include a lot of extraneous stuff.

But here's the flag code:

$flags = array();
// Exported flag: "Contact List".
$flags['contact_list'] = array(
  'content_type' => 'user',
  'title' => 'Contact List',
  'global' => 0,
  'types' => array(),
  'flag_short' => 'Add to contact list',
  'flag_long' => '',
  'flag_message' => '',
  'unflag_short' => 'Remove from contact list',
  'unflag_long' => '',
  'unflag_message' => '',
  'unflag_denied_text' => '',
  'link_type' => 'normal',
  'roles' => array(
    'flag' => array(
      0 => 2,
    ),
    'unflag' => array(
      0 => 2,
    ),
  ),
  'weight' => 0,
  'show_on_entity' => FALSE,
  'show_on_form' => 0,
  'access_author' => '',
  'show_on_profile' => 0,
  'access_uid' => 'others',
  'module' => '',
  'locked' => array(
    'name' => 'name',
  ),
  'api_version' => 2,
);
return $flags;

I can't export my view that shows the contact list because all the fields are specific to my site. However, this is basically just a view that shows the user profiles of users who have been flagged (formatted for the site) or a message that no one has been flagged yet by the user. I then added a link to this view to the privatemsg menu.

And here are a couple rules I added to give users visual confirmation that the flag actually did something:

{ "rules_show_confirmation_message_on_add_to_contact_list" : {
    "LABEL" : "Show confirmation message on add to contact list (en)",
    "PLUGIN" : "reaction rule",
    "REQUIRES" : [ "rules", "flag" ],
    "ON" : [ "flag_flagged_contact_list" ],
    "IF" : [
    ],
    "DO" : [
      { "drupal_message" : { "message" : "[flagged-user:name] has been added to your \u003Ca href=\u0022\/messages\/contact-list\u0022\u003Econtact list\u003C\/a\u003E." } }
    ]
  }
}

{ "rules_show_confirmation_message_on_remove_from_contact_list" : {
    "LABEL" : "Show confirmation message on remove from contact list (en)",
    "PLUGIN" : "reaction rule",
    "REQUIRES" : [ "rules", "flag" ],
    "ON" : [ "flag_unflagged_contact_list" ],
    "IF" : [
    ],
    "DO" : [
      { "drupal_message" : { "message" : "[flagged-user:name] has been removed from your \u003Ca href=\u0022\/messages\/contact-list\u0022\u003Econtact list\u003C\/a\u003E." } }
    ]
  }
}

Awesome. I will try to add some stuff to this and create a sandbox :)
