This  is  a  very good, if somewhat slow (on a 'basic' Amiga) GUI.  It
allows you to change everything about the visual presentation of a program and
the  Desktop.   Also all MUI-using programs will have a uniform look and feel.
Keyboard  shortcuts  can be setup and ALL MUI-progs can have an Arexx port.  I
know Mosaic will work on MUI2.0 onwards, the latest version is  2.3  available
from:

Aminet:	pub/aminet/dev/gui/mui23usr.lha
Demon:	pub/amiga/mosaic/mui23usr.lha

in  the same place is mui23dev.lha BUT you only need this if you want to write
your  own  applications.  Also please Register and get the keyfile.  It really
makes  a difference.  You can save everything in the MUI-prefs prog.  It's one
of  those  add-ons  that causes strong emotions in some.  ie Some love it some
loathe it, however if you want mosaic you MUST have it.
