It's greyed out for everyone (it would have been better to hide it altogether, I know). In future releases, it will pop up a window listing all available preview engines. That dialog will provide the possibility to enable or disable preview handlers, explicitly assign one or more file extension(s) to a specific preview handler, and change the preferred order of preview handlers.

I've already started on a hex viewer as preview handler. When given low priority (but higher than the 'file icon' handler), it will automatically be selected when all other handlers fail to preview a file. (The 'file icon' handler is currently the only one that is guaranteed to show something for any file or folder).

I guess a 'dump' view shouldn't be too difficult to add.

That would have been the first version; that just tried to display the file with whatever method it could.
In version 1.0.2, most preview handlers indicate whether they can handle the current file based on the file extension or, at most, a file signature at a specific location. They don't scan the entire file anymore.
