From Greg's Shareware:
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.
Version 2.7 now lets you edit file type and creator codes by clicking the file kind at the bottom of the Browser window or by pressing -. It also adds an option for live window resizing in the Browser Preferences box. (Note that live resizing is extremely processor intensive and works well only on very fast machines.) In addition, this version takes full advantage of the StuffIt Engine from Aladdin Systems, letting you directly manipulate the contents of StuffIt 5 archives. There are several other minor changes, including improvements to the file info displayed at the bottom of the Browser window and support for Appearance sound effects under Mac OS 8.5 or later.
