Features Toolbox
The Features Toolbox contains controls for displaying features including Borders, Fibers, Foci, and Labels onto the data being displayed on structures.
 
The Features Toolbox is not displayed by default, but is turned on with the button (or with View > Features Toolbox) and attached to the right side of the Viewing Area. It can also be
detached from the Workbench Window by left click + drag on the top of the Features Toolbox. To reattach, double click on the top of the Features Toolbox.

There are 4 tabs in the Features Toolbox, each controlling a different kind of feature's display:
These tabs are inactive (grayed-out) if no files are loaded containing a particular Feature.
