Systems and techniques to provide access to shared content are disclosed. In various embodiments, a user input indicating a set of selected sharing users that have shared content with a viewing user is received via a filter definition user interface. A combined set of shared content comprising content that has been shared with the viewing user by one or more sharing users included in said set of selected sharing users is determined based at least in part on the indication. A display is provided that includes for at least a subset of shared content in the combined set a user-selectable visual representation of the shared content.
