Why is fixed width font used on the displays and exports??
Fixed width font is your friend when it comes to laying out pages and exports like this site does. If you have experience in the past with online tabs, you’ll be familiar with this. By using fixed width, all letters and spaces take up the same width (like an old typewriter) so lining up tabs or chords with words becomes much easier and you don’t lose formatting and widths with different letters.
