URL shortener plugin

Can anyone tell me how the URL shortener plugin is supposed to work? Nothing happens when one clicks on the "Setup..." button for the plugin and nothing happens when one selects the option to copy a shortened URL for a selected download (tested for eD2k and BitTorrent downloads). If the plugin only works for certain kinds of downloads, maybe the option should be grayed out for all other ones...
EDIT: OK, it seems as if the URL is copied, but as there is no visual queue, one does not notice that. Maybe a small window similar to the copy URI window could be opened showing the newly generated URL? Like this the user could be given visual feedback that the operation was successful...
