Overview
An editor window is used as a base to display the GUI and support all the user interactions for a specific functionality. In Unity, most of the graphical elements you see are rendered over an editor window, and these can float freely or can be docked as a tab; these can be simple or complex depending of what they need to achieve. See the editor window in the following screenshot:
All the editor windows extend from the EditorWindow class, which is to be used in order to create our own custom editor windows.
In this chapter, you will learn how to create a custom editor window implementing a Palette, a window that will display the level piece prefabs of the video game.

The goals here are:
Implementing a category system
