Presented are a method, a system, and a computer program product for a unified graphical user interface for computing devices, enabling assembly of digital content for transmission to a plurality of network-based target destinations. The process may be initiated using content newly created or stored on the device, or using content accessible to the device by network connection. Destinations may be any communications services or upload destinations to which the device has access, and for some types of communication may be customized for singular recipients or groups of recipients. Icons representing content and one or more destinations are associated by user actions in the interface to establish the transmission to be executed. The interface also enables launching of applications installed on the device that are represented by the target destination icons. Embodiments described include those suited to both cursor-controlled devices and touchscreen-controlled devices.
