Scene Tool

The "Windows " section is a collection of specific windows that are available in the current Editor Mode (Scene, Navigation, Model, etc.)

Note that some windows are already activated and present by default.

As far as the Scene Editor mode is concerned, they are:

Properties – a window showing current properties of a selected object (Object Tab), Scene Editor (Tool Tab), and Special Debug Properties (Debug Tab).
Level Errors – a window for level-specific warnings & errors.
Selection Info – statistics on the selected object.

Please note that the "Selection Info" window is obsolete since the same information is visible at the bottom of the Scene Editor.
Objects List – the main list of objects already placed at the level, along with their hierarchical relations.
Entity List – a list of objects that can be placed at the level, as well as set up rules for showing or not showing specific types of objects.
Entity Filter – a window for shortlisting some objects into frequently accessed arrays for a more handy way to work with them.
Exposed Properties – a window to edit and construct lists of Exposed Properties for Group and Prefab objects.
Vegetation Tool – a window to edit and set up Brush Utilities for the Foliage feature.
Layers – the list of layers on this level.
