In an approach for modifying a user interface for a user of an application, a processor receives a plurality of actions for a user of an application. A processor generates a unique identifier for each action of the plurality of actions. A processor generates a unique string of the generated unique identifiers for each action of the plurality of actions. A processor determines that a portion of a pattern of the unique string matches, within a predetermined threshold, a portion of a pattern of a history of usage of a set of users of the application. A processor modifies a user interface of the application, for the user, based on the portion of the pattern of the matched unique string, within the predetermined threshold, the portion of the pattern of the history of usage.
