Can custom book data be displayed in a custom column?
I store a key called 'goodreads_id' in the plugin data store for books using db.add_custom_book_data() as recommended here and it is working great.
I am wondering if it is possible (for if a user wanted it) to display that value in a custom column. Alternatively for example have a column that indicates whether the value is populated. So users could see which books they have linked to Goodreads (and search based on this).
I had a brief look at program template functions, but I couldn't obviously see how you would have access to the custom book data.
Is it possible? I know chaley loves a challenge...
