[Suggestion] Setting parameter to allow default tag for upload

Thanks for your plugin – saving my day!
I am writing a plugin and the user can upload files via the media uploader. I would like that a media-tag should automatically be assigned to upload depending on my plugin page.

Here is the hack I used in mediatags_admin.php @#488

$media_tags_default=(isset($_GET["media-tags-default"]) && ($_GET["tab"]=="type") || !isset($_GET["type"])) ? $_GET["media-tags-default"] : ""; //<- probably not used!!
        if(!$media_tags_default){
          $qs=  parse_url($_SERVER["HTTP_REFERER"], PHP_URL_QUERY);
          parse_str($qs, $get_array);
          if(isset($get_array["media-tags-default"]) &&(!isset($get_array["type"]) || $get_array["tab"]=="type" )){
            $media_tags_default=$get_array["media-tags-default"];
          }

and then injected $media_tags_default a few lines later

$form_fields['media-meta'] = array(
       		'label' => __('Media-Tags:', MEDIA_TAGS_I18N_DOMAIN),
   			'input' => 'html',
   			'html' => "<input type='text' name='attachments[$post->ID][media_tags_input]'
				id='attachments[$post->ID][media_tags_input]'
       			size='50' value='<strong>$media_tags_default</strong>' />
				$post_media_tags_fields "
		);

Basically as uploads are handled via ajax to async.php I look at referer to get default tag. I also check the tab=type so it should only inject on upload page.
usage: to set default tab for upload – /wp-admin/media-upload.php?&tab=type&media-default-tags=my_default_tag

It seems to work! Would be great if you can include feature in future version.
Also the media-tags are not getting included in wordpress 3.5 – USING BACKWARDS COMPATIBLE media-upload.php
