Amiga WIMP GUI Interfaces
Starting from the original Amiga WIMP standard GUI called Workbench, Amiga interfaces were enhanced by third-party developers. Amiga users are free to replace the original Workbench interface with these: Scalos and Directory Opus. The standard GUI toolkit, calledIntuition, was enhanced in OS2.x with the introduction of GadTools and third parties created their own toolkits such as Magic User Interface (MUI),(the standard on MorphOS systems), and ClassAct, which then evolved into ReAction GUI (the standard GUI on AmigaOS 4.0).
