The maximum number is a threshold that is only applicable when Always show tasks filtering is set to No. If the number of items in a user's inbox exceeds the specified threshold, tasks filtering is reinstated until the number drops below the threshold.
The Show step name column site preference determines when the step name of a workflow is displayed in the list view.
The Maximum number of rows to return site preference determines the number of workflows that are displayed. The maximum number is 1000.
