If you have questions or problems, just ask.

I am not sure, if a column isn't being shown in the booklist, does it still populate and make the program slow?
Assuming you are running calibre 7.7, composite columns are evaluated when the value is needed for a book, such as when:
  • the book is shown in book details.
  • the book is shown in the booklist.
  • you sort on the column.
  • you search on the column.
If the column isn't shown in the book list then the last 3 won't happen unless you specifically use something like Search or Sort by to reference the column.

Versions of calibre before 7.7 would evaluate the columns if book details might be shown even if the details never were actually shown. Because of this, scrolling through the booklist could be slow. I hope that problem is now gone.

I need to really learn how to code and make templates. I have actually used Chat AI for creating scripts for stuff in the past to go through batches of files for things. It actually worked!
I'm glad for that it has worked for you. I must confess, though, that I find it hard to believe that generative AI will write correct & efficient code. But then I come from 60's-70's schools of computing, when even making a program do *anything* was a challenge.
