A system for managing visual interface content encompassing primary visual interface content and adjunct visual interface content includes a processing unit, a primary display apparatus, a memory, and a set of display-enabled user input apparatuses. The system can be configured to direct or perform visual interface content management operations including selectively establishing associations or mappings between particular adjunct visual interface content and portions of a display-enabled user input apparatus and possibly portions of the primary display apparatus in response to user input; displaying primary visual interface content using the primary display apparatus; displaying adjunct visual interface content using a display-enabled input apparatus, where the first adjunct visual interface content includes visual information that corresponds to a portion of a visual environment absent from the primary display apparatus and which indicates an in-application event; and progressively displaying updated adjunct visual interface content on an automatic basis and/or in response to user input during application program execution using a display-enabled user input apparatus.
