The History tab lets you specify options that concern the multi-history list view.
Sort history by latest first: When selected, the list of history timelines is sorted by the order in which the rows were added to the list, with the most recently added item first. When cleared, the list of history timelines is sorted alphabetically by vehicle or driver name.
Open History Details tab when showing a specific event: When selected, pressing a link that opens a history from another page such as Driver Forms, Insight Alert Inbox, or Dashboard, causes the vehicle pop-up to be opened to the history tab with the specified event selected in the list.
Indicate in history if the start and end times are unknown: When selected, if a vehicle's history is unknown (typically, this occurs if a vehicle is stopped for three or more consecutive days) the history is shown in gray without a start or end time on the History tab Gantt chart.
