Change the workspace layout in Final Cut Pro for Mac
Final Cut Pro comes with a set of predefined workspace layouts that determine the size and location of the main areas of the Final Cut Pro window, including the browser, the viewer, the inspector, and the timeline.
If none of the existing workspace layouts meet your needs, you can create and save additional layouts. After you save a custom workspace layout, you can easily share it with others. When you create custom layouts, you can include additional areas, such as the timeline index, the event viewer, the comparison viewer, and the audio meters.
In Final Cut Pro, choose Window > Workspaces, then choose a layout from the submenu.
In Final Cut Pro, arrange the areas of the main window the way you want them.
