Third fold allows you to play with fonts and set you your preferred one. The settings you do
here are for all EPUB or MOBI documents that you will open.
You can set up your preferred font from the list (the list can be enlarged when you click
“Select other”).
Please note that “Publisher’s font” is a font and it’s size that your e-book publisher chosen
for his book. It is not always the most agreable one. If you choose “Publisher’s font” option
the font shape and size for all e-books will differ.
