 **Main Viewport**: Due to common usage and backward compatibility reasons, the system currently enforces the creation of one _Main Viewport_ which is typically the main application window of the user application. The _Main Viewport_ is also a _Host Viewport_. In most traditional applications, the _Main Viewport_ has _Platform Decorations_ enabled when not maximized, and has _Platform Decorations_ disabled when fullscreen. In the future we would like to completely remove the concept of a "Main Viewport" and instead allow the application to freely create zero, one or more _Host Viewports_. Most games applications will create one of them, whereas most desktop applications are expected to create none. Under this scheme, an application creating no _Host Viewport_ would have every _ImGui Window_ using an individual _Platform Window_ with _Platform Decorations_ disabled. It would become the application's responsibility to shutdown when all the windows are closed.
 
-**Viewport**: The Dear ImGui representation of a _Platform Window_. When a _Viewport_ is active, Dear ImGui creates a _Platform Window_ for it. Whether the _Platform Window_ has _Platform Decorations_ enabled currently depends on the `io.ConfigViewportsNoDecoration` flag which gets turned into a `ImGuiViewportFlags_NoDecoration` for the _Platform Backend_ to honor.
