You can open multiple tabs in the same project window, which you can use to display multiple layouts or different views of the same layout. For example, you can show your full score layout in page view in one tab and in galley view in another tab.
Each tab can contain a separate layout or a different view of a layout already open in another tab or window. Whenever you open a new tab, you are prompted to select a layout that you want to display in the tab.
You can find tabs in the tab bar, located at the top of the music area, below the toolbar. If no tabs are shown, click Show Tabs in the toolbar.

Result
