The main work area is where data is viewed and manipulated.
Any view of data can be opened by simply clicking on it from the left hand panel. Views for Extended entities can be found beneath the entity on which they are based. The following right click options are available from the same list:
Delete: Remove this item.
Select as Default: When this entity is viewed from another, for example when Defects are viewed from Tasks, this is the view that will be used to display the data. This option is only available for non-system level Views. Layouts have an option to Delete and Select for Display Default.
Select for Drill Down: When the drill-down option is selected from a dashboard or chart for this entity, this is the view that will be used to display the data. This option is only available for non-system level Views.
