Just got a trackback on my recent post about QuickLook which led to this site:
http://www.quicklookplugins.com/
which is a directory of QuickLook plugins. I already have the FLV, ZIP, Folder view, and XML ones. None of the others listed there seem to be vital for me right now, but they might for you, depending on what type of files you deal with a lot. Also, it’s a good feed to subscribe to, so when new plugins come out or are discovered, you’ll know about them.
Thanks, Keith!
