The View Panel takes up mpst of the main window and serves as the gateway to the program's viewports, which allow visualizing and interacting with your 3D environment.
By default, the View Panel is subdivided into four viewports showing three orthographic views and a 3D perspective view.
You can customize the View Panel to show three, two, or just a single viewport, depending on your specific needs.
Each viewport can be configured to display a 3D perspective view or any of the available orthographic views.

This mode enables you to look around by moving the mouse and navigate using the WASD keys for forward, left, backward, and right movements. You can also use the mouse wheel for zooming in orthographic viewports or controlling the camera's distance in 3D perspective viewports.
