it is based on magellan that creates everything independently
the distribution includes all sort of toolkits, of course gadtools and intuition, Zune (MUI reimplementation), MUI 3.8 and others
the specific aros preferences are f.e. Zune
Many MUI-Applications work with Zune but not all. It is possible to change to MUI 3.8 and use it (as long you not need aros preferences). Then f.e. iBrowse works on it.
It also includes packer support, many viewers and players (doubleclick on file), preinstalled whdload and others
