12. A computer-implemented method comprising: outputting, for display, a carousel display including a plurality of active document representations, wherein each of the plurality of active document representations includes a document viewport portion of content from a corresponding active document, and the carousel display is operable, responsive to receiving an indication of a first user gesture selecting a first active document representation from the plurality of active document representations, to cause a full view of the corresponding active document to be output for display; monitoring, for the first active document representation, an inactivity period time value representing a period of time during which the corresponding active document has not been accessed; and decreasing a size of the first active document representation relative to other active document representations from the plurality of active document representations based on the inactivity period time value.
