Few features missing in iBooks app

Hi,

I have around 3,000 books on my iPad (iPad 2, bought in 2011). I was reading a book yesterday and at the same time I downloaded a PDF in my library. The book that I was reading was closed, and the problem was that I had several such books with the same name: " the hardy boys". Now when I did a search for all hardy boys, I was shown a list of matching books. I opened one of the books, but that wasn't the one I was readin, so I moved back to library, and puff.. The search list was gone. So I had to again scroll up to the top (please note 3000 books, and i am at letter "t" at the bottom). I had to repeat this again and again just find which book I was last reading. I really feel some features would come in very handy. Below is the list for the same:

1. A scroll bar, it becomes a pain to scroll up and down without any scroll bar.

2. Make the search field always visible when user is in library.

3. A separate list of read books, sorted on the basis of recently closed.

Hope the message reaches to concerned to department.

Regards.
