When creating Operator accounts, additional options can be assigned depending on how much access each Operator must have when running test scripts. Unchecking any box will remove its corresponding tab in the Worklist and/or Reference pane(s).
The Operator Test Options checkbox corresponds to the tabs and console options available on the Test Execution screen. Any unchecked box will result in the tab or console option not appearing for the Operator.
