BookLibary Component Support

I like the "Books Library" very well and I also would purchase the pro-version.

But one very important feature (for me) is missing yet:
The ratings-display do not show the users-average ratings.

It doesn´t matter how many times the users rate a book with 5 stars - their ratings does not influence the summary-rating of this book (i.e. in the books-overwiew directory). Why does it not?

It would be very essential for the concept of my site, that the site users could rate the books - and the users could see this summary at the books-overwiew-directory.

1. Please, is there any possibility to change this, to the users ratings influences the summary-rating of each book?

2. When this would be not possible - is there at least any possibility to remove the ratings completely and switch this function off?

Thank you for your help, regards!
