Usages
The Usages tab of the Snapshot Viewer is only available when you right-click on a task in the Source/Destination Tasks tab or the Equipment tab of the Snapshot Viewer - or right-click on a Solid in the Animation view - and select Find Usages.
The Usages tab allows you to see current Dependencies, Equipment that will be available to work the Task, and any relevant Destination Paths.
Double-clicking on any Source Path option will take you to the relevant section of the Equipment tab.
