Use with Kindle or mobi files?

I use EF to manage everything - work, home, hobbies. Recently I’ve started buying books from Kindle. Is there any way to include Kindle and other ebook formatted documents? I have fooled with converting to PDFs, but have not found a good solution.

Presumably the copy-protected files won’t work (.AZW format) but is there a way to handle others like .mobi? Has anyone found a work flow for this?

Of course, you can store any type of file in EagleFiler. For the formats that it doesn’t natively understand, it can use plug-ins. This page has a Quick Look plug-in for viewing .mobi files. I wonder whether someone’s written a Spotlight plug-in for searching them.
