||The World-wide web is becoming an invaluable source for the information needs of many users. However, current browsers are still primitive, in that they do not support many of the navigation needs of users, as indicated by user studies. They do not provide an overview and a sense of location in the information structure being browsed.

It provides a flexible environment where users can quickly organize, filter, and restructure the information on the screen as they reformulate their goals.
