You can switch view to Tab view, and all opened documents will be as Tabs:
You have two ways for switch between sub-windows and tabs view mode:
In "Window" menu you can select the item "Sub Windows" or "Tab Windows" for switch to necessary view mode
In application settings in "Main" tab you can check/uncheck "Document view"
