=+that allows tablet users to organize and categorize electronic documents of several types under user-defined tabs. For example, a kitchen remodeling project might require a pdf catalog, a jpg or
=+under a Cabinetry tab. Once defined, the binder and its tab content can be stored either on the tablet or on some cloud storage. The application needs to provide five key func-tions: binder and tab
