Hierarchical folders in the Leopard Dock with Quay
Still hate Stacks in the Leopard Dock? Rainer Brockerhoff has just released version 1.0 of Quay, his Leopard-or-later utility to give you back hierarchical browsing of folders in the Dock.
It uses no hacks or hidden features, and actually gives you a fair bit more functionality than Tiger’s Dock used to. €7 shareware (about $10).
