thank you for the answer. As you have told I did a blank page (that in the future will be charapter presentation) and colorized it, a good feature should be anyhow, that you can colorize a entire chapter with buttoncolors something similar to pages, but referring to all the chapter/book (<chapter buttoncolor="0x999999" >) or (<book buttoncolor="0x999999"), taking always the preference of the less general one (i mean : color preference in order page>chapter>book) this way you can format the links in a very simple way. I would like to help with the programing of this, but I'm afraid, that my AS3 programing is very basic :S
