How does one assign a custom url for the tweet button instead of defaulting to the node in question? I would like to be able to alter the url that the tweet button uses because the node in question is only accessed via a panels page - and furthermore, in the case of , for example, a facebook app, the node would be seen through an iFrame. The url on the tweet should point to the facebook app - not to the drupal node.
Is there a table that tweetbutton already uses where the data-url property can be stored - or does this require a patch for the hook_nodeapi to form-alter the edit and view ops. to lookup for a data-url?
