Intuition

Intuition is the windowing system and user interface (UI) engine of AmigaOS.

It was developed almost entirely by RJ Mical, Intuition should not be confused with Workbench, the AmigaOS spatial file manager, which relies on Intuition for handling windows and input events.

Intuition is the internal widget and graphics system. It is not implemented primarily as an application-managed graphics library, but rather as a separate task that maintains the state of all the standard UI elements independently from the application. This makes it singularly responsive because UI gadgets are live even when the application is busy. The Intuition task is driven by user events through the mouse, keyboard, and other input devices. It also arbitrates collisions of the mouse pointer and icons and control of "animated icons".
