The REST API includes the "next" property on the JSON, which indicates that another page of activities is available for fetching:
{ results: [], next: '/api/v1.0/feed/<< feed_group >>/<< feed_id >>/?api_key=<< api_key >>&id_lt=<< next_activity_id >>&limit=<< activity_limit >>' }
This is not being exposed on the StreamResponse object. It would be very helpful to have this property, as it could allow having an indicator that there is at least one more page available, since there is not a way to get the total count of activities on a feed for a specific user.
