I'm reading a difficult, hard to read book right now. I get bored, my mind wanders and just give up reading it.
Can there be tags, or another metadata property, or filter type, added to all the books that tell us the reading level of the book.
Beginner, General, Advanced. Something like that. Beginners can sort their library by beginner books and choose easier things to read for now.
Another tag for if the doctrines are beginner friendly or advanced. Milk or meat.
Can there also be tags for modern or classic.
Another tag for renowned. The very popular authors and books of the past, household names. We could sort books by that, if we want to see all the books we have by those renowned authors.
Another tag for Denomination. Even if the book isn't part of a denomination library bundle, the denominations still don't agree about many things, so it's best to be able to quickly see which denomination the author hails from.
