8 years ago Not sure I can do anything about that - the headers are formatted by the leanpub engine and there are no options to customize them. I'll try to ask leanpub to introduce a feature to make the headers customizable. By the way, I'd like to add you to the "Thank you" section of the book. Please let me know (either here or via the "email the author" link from leanpub page) what name should I put.
Names of the chapters in the upper left corner of the page blend in into the text. It is really confusing in case of a code snippet spanning across two pages (for example page 20). Maybe it would be good to make it more distinctive. or consider putting a little horizontal line to clearly separate page header from the contents.
