A must-have freeware
program for Amiga
that gives "graphical enhancement [...] allowing palette
-independent icons in up to 256 colors
In other words, it gives WorkBench 3.x a lot more modern look: it junks those 4-color icons from WorkBench and allows you to use truly cool icons - while preserving the old paletted icons! Similiar in spirit than MagicWB but it's freeware.
