> Greg Landweber's comments on his browser:
>
> "Do you think the Finder is too slow and clumsy when navigating
> through your folder structure? Do you perhaps use a hierarchical
> Apple menu utility but are tired of zigging and zagging your mouse
> from submenu to submenu? Or maybe you just like miniature icons. If
> so, then you should try Greg's Browser. Displaying multiple folders
> side-by-side in a single window, Greg's Browser lets you
> simultaneously see the contents of a folder, its parent, and a
> subfolder, providing a quick and easy way of moving both up and down
> through your folder hierarchy. Greg's Browser can browse into
> StuffIt archives just like they were normal folders, and it uses the
> StuffIt Engine from Aladdin Systems for stuffing, binhexing, and
> expanding files."
