Make Quicklook Better

Unlike the snazzy but arguably useless addition of Cover Flow navigation to OS X, Quicklook is one of the best UI features of Leopard. You can page through Word docs and pdf's, preview images, all without waiting for their apps to load (a serious time suck for apps like Word, Adobe Reader, and Photoshop). This can seriously increase your productivity when trying to find that one file whose name your forgot, or quickly lookup info in a pdf or Word file.
However, for Web developers, it would be nice if we could Quicklook our javascript, css, and actionscript files too. It would be even better if it provided color coding to make visually parsing our html, php, and other text-based files even easier.
Now we can thanks to the one of the great Quicklook plugins listed on qlplugins.com. The plugin is hosted here on Google Code. If you develop on Leopard, drop in this plugin to your /Library/Quicklook folder and speed up your development time.
Even if you are not a dev, the Folder and Archive plugins are very useful - allowing you to preview the contents of a folder or a file archive (like a zipped file) without opening or uncompressing them respectively. I have found these last two plugins so helpful that I am surprised the functionality didn't come stock in Quicklook.
What sort of customization have you done to your Leopard install? Please share!
