How to preview any file in Lion? I love OS X Lion's feature to preview some files without opening them. Is there a way to register new file extension? For example, Drupal module extension ".module", which is a text file.
To preview files, you need a QuickLook plugin. Special thanks to Jason Salaz for providing this list:

And Jason's specially crafted Google search.

It looks like there is support for the Drupal .module via this plugin.
