I’ve made the margins even for every page to make reading more comfortable. Heading and image positions are fixed, as well as a new Table of Contents, which links to the particular sections and corresponds to the proper pages. I’ve removed the alphabetic index in the end as well as all page references, which were untrue due to the change in format. Basically, it’s what a handbook or manual should be – without distractions, easy to use and concentrated on the topic.
