To find a task, first click "List Mode".  This will make it easier to refine your search with custom filters.


Next, enter your filters in the fields at the left of the screen.

Example: "delivery" for task type and "200 - Dispatched, Message sent" as status.

Then, Click "Apply".


Your tasks will now be filtered and will appear to the right.


Note that some fields allow many choices, making this tool very flexible.
