A new "hack" for Finder is in the works, and it's pretty darn cool. TotalFinder adds tabs, Visor-like functionality and a few other goodies (with more on the way) to your plain, vanilla Finder setup. If you're skittish, though, don't jump just yet. TotalFinder is alpha, and not in that way that developers label software just to be safe. It's really, really alpha. TotalFinder runs as a SIMBL plugin, too, which can (in some cases) cause some system instability in and of itself. However, if you've got the apples for it, it's a very cool new way to soup up your Finder.
In its current state, it does a few simple -- yet amazingly useful -- things, starting with adding tabs to Finder. Honestly, we got tabs in Terminal before Finder? This catches us up a little bit. The Visor feature (which is optional), assigns a hotkey that makes your tabbed Finder window slide onto the screen and disappear when you're not using it. It's take-or-leave for me at this point; it's cool, but it takes a lot of getting used to, especially for window-to-window file dragging within Finder. You can't currently drop files onto other tabs, so some problems arise in that situation. The other features include preventing .DS_Store file creation and sorting file listings with folders grouped on top.
For now, I'm sticking with Path Finder for my souped-up Finder needs, but TotalFinder has the potential to bring Finder into its own after years of relatively few improvements. You can grab a copy to try out (for free) at BinaryAge, and note that it comes with an uninstall script that will wipe it clean off your system if you don't like it.
