If you're not satisfied with Stacks, HierarchicalDock bring hierarchical menus to your Mac Leopard.
Similar to Quay, HierarchicalDock is for all you people out there who aren't really convinced by Stacks and still prefer good old hierarchical menus. The application is fairly easy to work with, fast and responsive. We like how you can quickly copy file paths just by holding down the Ctrl button.
HierarchicalDock will show all files, including invisible ones. The QuickLook Preview is a nice way of getting a glance at files without actuallly opening them up. Users will also appreciate quickly opening up folders just by holding down shift . You can only sort elements alphabetically, by creation date and last used date, but that should be enough to find your files quickly.
HierarchicalDock brings back hierarchical menus on your Mac Leopard. Despite limited sorting possibilities, it's very quick and responsive.
