OS9-style Window Management in OSX

I don’t have a PowerBook yet, but I'm already collecting URLs for useful Mac software for when I get one ;). One such utility that looks interesting is the plainly-named Classic Window Management — it’s a freeware app that sets OSX to use OS9-style bring-to-front rules for application windows.

Classic Window Management gives you the option to have windows in Mac OS X behave like they did in Mac OS 9, where all of an application's windows stayed grouped together. So when you click on one window, all windows belonging to that application come to the front. […]

If that still doesn't make sense, just check out the site — the illustrations there should clarify things. Of course, not having a Mac, I can’t say that I’ve tried this app, but it can't be that bad if both Zeldman and Eric Meyer like it ;).
