Modifying fileds in the Add Book form

Overall, I'm very happy with this mod!  It performs well and is a good value.

However, I'd like to drop some of the fields in the Create Book form:

http://yoursitename.com/social/m/book/administration/create

and I can't find a way to do this.

Also, is there a way to display book lists without an image?  The images look good, but if an image isn't uploaded, the default is pretty ugly (no-photo-110.png) and I can't figure out how to replace it, even though I did change the php code in BxBookPageMain.php

Thanks for any assistance!

I've figured some of this out.  To remove some fields, you simply comment them out in BxBookFormAdd.php.  For example, to remove awards:

//    'awards' => array(
//                    'type' => 'textarea',
//                    'name' => 'awards',
//                    'caption' => _t('_modzzz_book_form_caption_awards'),
//                    'required' => false,
//                    'html' => 1,
//                    'db' => array (
//                        'pass' => 'XssHtml',
//                    ),                   
//                ),

For sounds or videos, there's additional code, but it's well-documented as easy enough to spot.
