They took away a lot features, you can no longer search by genres, authors, etc. Basically you need to know exactly what you're looking for to find it making new discoveries impossible. You can no longer find free comics. You will be seeing sales for comics that are not available for purchase. An issue which you read last will be displayed on the bottom of screen and there's nothing you can do about it and it will cover content including the Buy Now button at checkout. Very convenient indeed.
