Hi Kiwidude. First of all thanks for great plugin. It's really useful, but there's an error, I want report. I have custom bool column named read. All book are marked as not read (N). I configured Reading List to change this column when book is removed from list (which suppose to mean I've read book, and column should change its value to T). When I remove book from list I got error
In calibre behaviour options there's checkbox to change y/n columns to tristate, but I have same error even if unchecked this. Can you fix this error? Many thanks.
