Finally an Open Source gem
I tried Library Notes early last year and I fell in love with its simplicity and abundance of features. I have tried other paid options before, but they are way too limited in what they offer for free (I think the book limit is less than 20). What I would like to see added is an import feature for book collections. There is an app called Libby that lets you export all books read or unread as a CSV file or json file. Being able to import these into Library Notes, and take notes would make my reading experience that much more fruitful. I listen to audiobooks from Libby and it would be nice for the app to recognize audiobooks and playtimes. Anyway, I love the app nonetheless and the developer is great.
