Space.dock provides virtual workspaces to help you organize your desktop. Opening Space.dock causes non-hidden applications to be added to the first workspace. Just open the dockling menu to switch to other workspaces or to add more. When you switch to other workspaces, current workspaces become hidden. System components like the Dock and the Finder are not hidden when changing workspaces. For more information, including on updates, please read the documentation or visit the home page.
