Gives you hierarchical menus in your Leopard Dock.
HierarchicalDock gives you hierarchical menu navigation of folders sitting in your Dock. As of Mac OS X 10.5, Leopard doesn't support going through more than 1 folder deep for stacks in your Dock. This makes it easier to navigate multiple folders deep with a simple click.
What's new in HierarchicalDock
Fixed a bug that prevented creation of folders with "/" in the filename
Show Finder's color labels
Show number of items of subfolders
Fixed .essdocker extension bug for good (you may have to re-add folders with this new version)
