I've attached a photo of the K4 after using the font/margin plugin via calibre. On after thought I should make a non-modified photo too, so I will and then add it to this post. BTW, that is not a scratch near the bottom part of the bezel I've got two cats and that is a cat hair!
I'm using
PMN Caecilia 85 Heavy with margins set to 16. (Default margins is 40.)
EDIT: I added the photo showing the system default font/margin settings.
