3D FlipBook - Looking for these features

Looking for these features

1. User management integration - wherein users need to login and can only download, read, comment and rate the materials if they are verified users.
2. Ratings and comment - Users can rate and comment on the material. Rating can be star ratings.
3. Bookmarks per user - I know this is big just throwing it out there if there is such an option.
4. Category display - can i manage the spacing per material? when i'm trying to use this in free version images have no space from each other.

interested on purchasing pro version hope for your quick reply.

thanks,

allan
