Keeping track of your books & subtitle customizations

I'm curious to see how many people customize their metadata to add more info about a book! I'd love to see what changes you made

I get lazy to long press on a book and click "book details" so I've substituted the scarcely used subtitle section for word counts followed by the genres or tropes. If there's no genres/tropes then I'll replace this with the hours/minutes needed to read a book. Then I categorize the books into collections by word count, season/mood, or genre
