For those who want an AmigaOS 3.1 look in MorphOS, then this skin is a nice skin to get. Download it and transform your MorphOS look into AmigaOS 3.1 or maybe change MorphOS totally to AmigaOS 3.1?

Yes, it is possible. With MorphOS ability to run Classic Amiga Software this is a perfect skin to have?
