Thank you for the interface translation; it's helpful for using different Calibre languages.
Here's an example with this book:
https://www.goodreads.com/book/show/61401172 I use Goodreads to track my reading and the Goodreads Sync and Goodreads plugins to download metadata.
The Goodreads metadata plugin has a unique feature: you can edit the list of names for the literary hierarchies. For example, this book has these: Genres: Fantasy
Fiction
Historical Fiction
Steampunk
Mystery
Queer
Historical
If it finds "Fantasy" and you've edited the "Fantasy" field to your language, it will recognize it as such. For example, if it finds "Fantasy" and I edited "Fantasia" (in Spanish), it will display "Fantasia." I've attached a screenshot.
