Is there a Quick Look plug-in that works with ZIP files, and that lists all the files contained in the archive? It is also fine if it lists at least some of the files.
Well, Better Zip does a fair job.
Another alternative is The Archive Browser. It is a commercial tool as well but will show the contents of various file types.
From the site:
The Archive Browser lets you easily peek into the archive, find the files you need, preview and extract them without unarchiving everything. Quick Look any file or folder and open them right from the archive
