See folder content previews in Quick Look in 10.5 and 10.6

I use QuickLook pretty much everyday while searching through folders.  I fin it most helpful when browsing documents, PDF's and media files like photos or videos. Until now if you ran across a nested folder ( a folder inside of another folder) QuickLook will just show you a pretty little aqua blue folder. But adding this little hake-a-round I found on Mac OS X Hints and you'll have a neat little semi-transparent folder to see your files in complete with a rotating animation of your files.

How Do You Do This You Say...Easy:

1. Force Quit/Relaunch Finder Using the Force Quite Menu  (or cmd + opt + esc)
2. Open Terminal Application (in your Utilities folder)
3. Enter or paste in the following command:

defaults write com.apple.Finder QLEnableXRayFolders 1

4. Relaunch Finder

[UPDATE: I was able to do this in 10.6.1 by just pasting the command into terminal without quitting the Finder.]

These are my before and afters.
