Is this uuid accessible as a calibre variable or would the opf file (metadata.opf in book dir?) need to be read in and searched?
The other concern I would have is that if this, f207657a-2b88-4763-95db-f37c0e536782, is an example of aforesaid uuid, it would create filenames much longer than I had in mind. Perfect for internal usage but no more meaningful to a user than my current basic

I think I might be trying to overthink this. The functionality of this cosmetic plugin is not internal to calibre, so I don't think precise rocket science is required as yet.
I really appreciate you techies joining in though
