Collapsible sections in the Photo Stream

When photos are sorted in the Photo Stream it would be nice to be able to collapse the sections to reduce the amount of scrolling required to find a specific section. For example, if the photos are sorted by Camera and the first Camera on the list is say an Agfa camera and you want to see photos from a Panasonic camera there is a lot of scrolling to do. If the Camera labelled sections could all be collapsed then the Panasonic section could be quickly located and then opened. It would be good to have individually collapsible and globally collapsible options. Perhaps through the right click menu.
