KURTTAPPE  My review of this plugin is highly varied. First of all, it's *way* better than not having any QuickLook preview at all. You can get a general feel for what is in the document. And the sidebar list of colors and fonts is an amazingly useful bonus that one really wouldn't expect.

*However*, the text in the documents does not get rendered. You can see where the linebreaks are and the general layout, but you can't read the text--it is replaced with blurry grey bars. So if you have two similar documents, you cannot tell them apart. Given that other QL plugins do render text I can't fathom why this one doesn't. The lack of text makes this feel like a Beta version where the authors say "Wait until the final; we'll get text working by then." But since it's been nearly 2 years since SneakPeak was released, nobody should be holding their breath that it will ever be added.

I don't want to join the "this costs too much" crowd except to say that for $20, it really should render text. Without that feature, this plugin should cost about half what it does. That's only fair.

KURTTAPPE  In answer to a previous question about finding alternative methods to do what AppleJack did, repairing permissions from the command line is fortunately very easy:

diskutil repairPermissions /

Note the capitalization of "Permissions". Hope this helps.

KURT TAPPE  I burned a test DVD of one of my partitions using Firestarter 1.0b6. No errors were reported during the process, but the resulting DVD would not even mount when inserted back into the very Mac that burned it. This was under MacOS X 10.3.4 on a 15" PowerBook G4/1.25.
