This plugin is looking pretty awesome!
Here's something that I think could be really good... At least I'd find it very, very valuable!
On the Edit Book page, I'd love to see an Excerpt area, like you see in Posts... And to guild the lilly, I'd like it if you included the hook to the TinyMCE editor, so that editing capability would be in both the main editor as well as the excerpt.
What I see right now, is if I use the Genre shortcode on a page, that page displays the Title, Featured Image, and "Read More" button. (oddly formatted btw)
I'd also like like the Author and an excerpt from the book page to appear as well.
I prefer the separate excerpt from the book page vs. using the first X-many words so that it can have different text from the Book Page -- Good for SEO!!
What do you say?
