My biggest problem is the way it displays books. If you have maybe a dozen or two dozen books in your library then I guess lithium is fine but if you're like me and you have hundreds of books it's a nightmare finding the one you want. And although there is a settings for choosing your book folder, it doesn't forget all the other books it had found previously. This app is unusable for an avid book reader.

I love this app so much that I got the pro version to support the developers. Now it has this terrible bug where you can't highlight anything without it grabbing a lot of extra text across pages, it is terrible and such an important feature in a ePub reader. I study books, I don't read novels. As soon as they fix is I'll come back and change my review

I have used Lithium Pro for years and read 100s of books with it. I have and at times used other readers, but Lithium is my go-to day in and day out. It is rock solid. It's configurability is not as extensive as some others, but the configurability available is perfectly chosen and easily accessed. This is important as I read in different environments so quickly adjusting font intensity or background color is very useful - I do such frequently. Lithium is the most usable reader I've found!
