A list authoring surface (LAS) is provided that includes a lightweight user interface component for entering, displaying, manipulating, and providing reminders for one or more tasks that takes the place of hand-written notes, scraps of paper, or “sticky” notes. The list authoring surface may be deployed across a multitude of software applications and may be readily accessed anywhere on a stationary or mobile desktop or display screen. Information may be manually or automatically entered into the list authoring surface user interface. An event timeline that uses a “fuzzy” reminder method allows for reminders to be associated with tasks where some tasks must be accomplished or must occur at hard dates/times, but where other tasks may be accomplished or may occur during soft or “fuzzy” date/time ranges.
