What Are Workspaces?
The Premiere Pro interface is made up of panels that are organized into a layout, and saved as a workspace. Premiere Pro comes with 9 factory-default workspaces: Assembly, Editing, Color, Effects, Audio, Libraries, Graphics, All Panels, and Metalogging. You can see by their names that Adobe has arranged the default workspaces by specific post-production tasks. Not a bad strategy for customizing your own Premiere Pro workspaces.
