US Patent 9710134 Smart contact lists

A list of contacts or other files displayed on a computer device may be customized such that an order of the list, or a visual appearance of one or more of the files in the list, may indicate the extent of a user's behavior or activity with regard to the one or more files. The list may be reordered based on the frequency or recency of events associated with such behavior or activity, thereby causing more frequently or recently accessed files to be ranked higher in a list, and less frequently or recently accessed files to be ranked lower in the list. Additionally, an aspect of the appearances of the files in the list may be modified to reflect a frequency or recency with which events associated with one or more of the files have occurred.
