Hi Kovid,
I am one of those guys who want a little more control about how calibre manages the files in its library
Basically, I'm putting all of the books in a given series into its own folder structure (
http://bugs.calibre-ebook.com/ticket/3208 ).
Would you accept a patch that makes determining the path from name, author and metadata configurable, the way your plugins work? That way, you would get all of us people with OCD off your back and I wouldn't have to patch my local installation every time you release a new version
If you want, I can open a new ticket for this and provide a patch during the weekend.
Regards,
Hakan
