After the refactoring plane was done, new structural features have been requested, and most of them couldn't take a place without rewrite the main module again, so the better solution was to implement those solutions in external modules, easy to mantain and modify without break the main project if something, depending also from external modules, would go wrong.

A first attempt has been done to allow a more easy way to extend the number of features reusing also the availables interfaces, of course there is much to do in this sense but at least the two plugins developed can be a good example to who want build more complex ones.

Service Links Displays
this is an interface to the Drupal module Display Suite, it defines more fields to be used with Display Suite using only the services selected in an appropriate column within the service selection page.
Service Links Sprites
this plugin help to limit the number of requests made to the server to show the icons used by static services.
