Hi - I am using Calibre Companion and I successfully added custom columns to my groupings but I was wondering if there is a way to add the custom columns to the listing of information you see for each book when you click on it. For instance, one of my custom columns contains an R for books that have been read. I would like this to show up when I click on a book and see that books information if the book has been read. Thanks.
