I read physical books, owned and from the library, on Kindle, and occasionally iPad for non-Kindle ebooks. I started to tag books with this status until I realized those were public. What I need is a way to note on a book how I read it (how I read it indicates where my notes are). Private tags seemed like an obvious option for this, since no one else needs to know format. But I need to be able to add this prior to leaving a review - private notes don’t seem like the right place. I’d also love to be able to filter or see reports based on book format, so maybe a new custom field is the way to go here? Open to whatever the team comes up with, just adding what I’d like to be able to do.
