The Code to open the book is there just modify the bottem of the xml file look for the sizeing of teh window and make it 30 longer (i think) the tag should be <cy></cy>
the problem with teh fadeing/back colour is i used the button graphics that already exist which is natually dark, i will try to draw some lighter buttons but it defeats the object that it was graphics independant, i will see what i can do for you.
I will make the Distribution Zip File include a Non and a With Book Version
the reason i left it out is as habit i type /boo (aka /book <page number> to open my spell book so the icon is redundant to me
