ClassAct is similar to MUI.
Not trolling your post, friend, but MUI have much more functionalities than just showing new icons on Workbench.
OK, so is ClassAct. It gives the Workbench the ability to recognize an archive by its type and gives a standard new style icon to it.
Example: you have some .jpeg images in a drawer of the HD
with no icons given to them. When you are running ClassAct and you open that drawer you'll see the icons with a little image with "jpeg" stated in them. Nice.
BTW: MUI and ClassAct don't clashes each other. :-)
