Additional Order Details in Order Email Notification

I am looking to do this as well. In particular the line items. subscribe

+1

There is a sandbox module: http://drupal.org/sandbox/paul.linney/1252292

With this I was able to craft my custom order email using theme template from this module.

subscribe. i also think there should be a better support for the notifications capabilities.
what about payment for this?

Maybe this help you http://drupal.org/project/commerce_email

thx maestrojed

You can create your own replacement patterns using the following example code. Note that $order contains all the order data. Use the devel module's dpm() to view the contents of $order and then format and return the data as desired.

/**
* Implements hook_token_info_alter().
*/
function MYMODULE_token_info_alter(&$info) {
  $info['tokens']['commerce-order']['custom-token'] = array(
    'name' => t('Custom token'),
    'description' => t('My custom commerce-order token.'),
  );
}

/**
* Implements hook_tokens().
*/
function MYMODULE_tokens($type, $tokens, array $data = array(), array $options = array()) {

  $url_options = array('absolute' => TRUE);

  if (isset($options['language'])) {
    $url_options['language'] = $options['language'];
    $language_code = $options['language']->language;
  }
  else {
    $language_code = NULL;
  }

  $sanitize = !empty($options['sanitize']);

  $replacements = array();

  if ($type == 'commerce-order' && !empty($data['commerce-order'])) {
    $order = $data['commerce-order'];

    foreach ($tokens as $name => $original) {
      switch ($name) {
        case 'custom-token':
          $replacements[$original] = 'MY OUTPUT';
          break;

      }
    }
  }

  return $replacements;
}

Commerce Message now provides a powerful solution.

Think bojanz was aiming at https://www.drupal.org/project/commerce_email not commerce message.

No, I wasn't.

yes sorry, just looked more into messages and I guess you were aiming at summary part of that module. So there are more ways to tackle this problem.
I apologize :)
