A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions readable by a device to cause the device to:

• receive multiple interfaces presented on a display screen, each of the multiple interfaces being where a user has visited at least one time, the multiple interfaces comprising at least one primary task interface, each of the multiple interfaces presenting at least one content item, the at least one primary task interface being an interface of an application different from applications of rest of the multiple interfaces;
• estimate a user engagement level with respect to content items presented via the rest of the multiple interfaces based on the user interaction with the content items across the rest of the multiple interfaces, the user interaction including the user transitioning from one of the multiple interfaces to another one of the multiple interfaces;
• determine a degree of user effectiveness with respect to progression toward completing a primary task presented via the primary task interface;
• select a content item from the rest of the multiple interfaces based on the user engagement level and the degree of user effectiveness, the content item including information from at least one of the rest of the multiple interface, to which the user transitioned a number of times from the primary task interface;
• and
• control a presentation of the selected content item on an unused portion of at least one of the multiple interfaces,
• the device caused to select the content based on determining that the degree of user effectiveness with respect to progression toward completing the primary task is below a threshold.

A system of controlling contents of interfaces, comprising:

• at least one hardware processor coupled with at least one memory device, the at least one hardware processor operable to at least:
• receive multiple interfaces opened via a computing device, each of the multiple interfaces being where a user has visited at least one time, the multiple interfaces comprising at least one primary task interface, each of the multiple interfaces presenting at least one content item, the at least one primary task interface being an interface of an application different from applications of rest of the multiple interfaces;
• estimate a user engagement level with respect to content items presented via the rest of the multiple interfaces based on the user interaction with the content items across the rest of the multiple interfaces, the user interaction including the user transitioning from one of the multiple interfaces to another one of the multiple interfaces;
• determine a degree of user effectiveness with respect to progression toward completing a primary task presented via the primary task interface;
• select a content item from the rest of the multiple interfaces based on the user engagement level and the degree of user effectiveness, the content item including information from at least one of the rest of the multiple interface, to which the user transitioned a number of times from the primary task interface;
• and
• control a presentation of the selected content item on an unused portion of at least one of the multiple interfaces,
• the at least one hardware processor operable to select the content based on determining that the degree of user effectiveness with respect to progression toward completing the primary task is below a threshold.
