To create a custom workspace in Adobe After Effects, which menu option do you use?

To create a custom workspace in Adobe After Effects, you use the option to save it as a new workspace, which allows you to store your preferred layout of panels for future use. When you select "Window" followed by "Workspace" and then "Save as New Workspace," After Effects captures the current arrangement of panels and settings you have configured. This is particularly useful for streamlining your workflow, as it allows you to switch back to a personalized setup that suits your specific project needs or preferences without having to rearrange panels each time.

The other choices do not provide the same functionality for creating and saving a personalized workspace. Options related to file, view, or edit do not directly address the functionality of saving a custom panel layout, which is why they are not applicable in this context.
