TidBITS Problem Solving: A Simple Hack To Fix Leopard's Stacks:It's a really beautiful hack, and to me one of the neatest aspects is that it comes to us from a Japanese Mac fan.
...Zen balance is now restored to my Desktop and Dock, and I find myself once again using Stacks to organize my current projects. For smaller folders the single-click access to the stack is surprisingly more convenient than right-clicking was under Tiger. And sorting by date modified makes even large directories useful as stacks, since I usually want to access the most recent files anyway.
Rumor has it that the Mac is starting to get a following in Japan. If true this will bring a new rush of invention and creativity to the platform.
