A user interface for a portable computing device provides two modes of operation. In a first mode, an inbox of all documents accessible by the portable computing device are presented. Each of the items in the inbox is selectable, and if selected, the user interface transitions to a second document presentation mode. In the document presentation mode, the user may annotate the document and upon providing a single input (selecting a submit button), the system automatically forwards the document (including the annotations) to the next state in the workflow. If the user transitions back to the inbox mode from the document presentation mode, no action is taken on the document but the strokes are stored with the document on the portable computing device.
