An entire new system was built, steering away from the traditional chronological list format of Craigslist and others, and designing an original system that gives more power and control to the user, while displaying more of the data visually. A very impressive feature is the gallery view, allowing users to see more images of listed items at once.
With C2, the listings within a given category are not merely listed; the user has the option to move between a list, a table and a gallery to view the information. In the gallery mode, only those listings containing images are loaded, and the images display in a photo matrix. As the user mouses over each photo, information is displayed in a floating window, such as ad description, price, and expiration date.
