Aspects of expanded icon navigation are described. In one example, the hierarchical structure of a network site accessible over a computer network is indexed to generate an indexed zone hierarchy of the network site. Access across the indexed zone hierarchy of the network site is monitored to assemble a collection of accessed resources on the network site. A resource at the network site is registered as a marked resource, and a marked resource anchor associated with the marked resource is generated. A number of branches of the marked resource anchor are them populated for the network site based on the indexed zone hierarchy of the network site, the marked resource, and the collection of accessed resources.
