Abstract: An automatic organization into topics for a browsing history. In one embodiment, a system identifies groups of browsing actions as related, and clusters the browsing history (e.g. a web browsing history) into sessions based on heuristics used to determine relationships. Latent semantic analysis can be used to determine the relationships which can be considered topics. User interfaces for displaying or otherwise presenting these sessions can include icons representative of topics, and these icons can have different sizes depending on a frequency of web page visits within a topic. The topics can be displayed in time ranges or in a cover flow view or both time ranges and cover flow view.

Abstract: Methods and apparatuses that generate a thumbnail image for each tab in a window based on a snapshot of the window providing interface for a presentation corresponding to the tab are described. An expanded tab bar may be displayed to replace a tab bar inside the window. One or more thumbnail images may be displayed in the expanded tab bar. A user interface operation may be detected on a particular thumbnail image in the expanded tab bar to update the window for providing interface for a particular presentation corresponding to the particular thumbnail.
