On Mac, Final Draft can show you all your open documents in multiple ways.
View > Show All Tabs
Going to View > Show All Tabs will display all open documents as tiles:
Click on a document tile to expand it to fill the Final Draft application window.
To close a document in this view, click the X at its upper left corner. If the document is unsaved, a standard Save window will be displayed.
To create a new document, click the tile with the plus sign.
View > Show / Hide Tab Bar
In macOS 10.15 Catalina -- Dock preferences, when the box for Prefer Tabs when Opening Documents -- Always is checked, and in macOS 11 Big Sur and later, in Preferences > General, Prefer Tabs Always When Opening Documents is checked, and Final Draft is launched, a tabbed view, similar to a web browser, is an option.
Select View > Show Tab Bar to display a tab for each open document. The user may switch from one to another by clicking its tab:
Right-clicking or Control + clicking on a tab offers options to close the tab, close other tabs, move the tab to a new window or show all tabs.
A tab may be closed by clicking the X on the left. Hold down the Option key on the keyboard and click the X to close all other tabs.
A new document type of the last-chosen template may be opened by clicking the plus sign at the right end of the Tab bar.
