When I click from month to day, or week, and the timescale shows a default 6am - 8pm day, if my task is somehow due outside of those hours, there is no indication that I have a task on that day, and I would have to scroll up or down to see it. Perhaps, in that case, when a task exists but is earlier or later than the current timescale is displaying, there could be some thin colored bar at the top of the time-window, that indicates that there's a task hidden, beyond the displayed hours.
