dissappointed that categories have been removed from app

I have been using the book and app for a few years and was really excited for the long awaited update. unfortunately, i can no longer search by categories, making the app almost useless when shopping. in fact, i dont plan on updating my iphone unless categories becomes available. i really hope that this functionality is returned to the app, even if it requires an additional charge. for me, the whole purpose of the app was to be able to leave the book at home. 5 star app, once i can search by categories. thanks!!!!
