For a theme I'm developing, I'd need to know if a node being displayed is the last or not, as I'd need to apply a custom CSS class to it. This is especially needed for category pages, if the number of posts doesn't reach the value that triggers Drupal pagination.
I've seen somebody else needed it too: http://drupal.org/node/17624, but they didn't file a request, so I'm doing it.
If someone could add this feature, or at least give pointers on how to do this, it'd be really appreciated.
