Hello ,on top of a ToC(Table of contents) for easier in-page navigation i will also enable in-book highlighting and zooming for custom reads .But most importantly maintain or improve the quality where possible. Also on top of the mobi kindle/Amazon format,i will throw in an iBook/Apple format as a bonus. Am ready for all these whenever you are. I will bid a bit lower since am still after ratings .You can check my reviews for experience and quality of work.
Regards ,Kevin
