I apologize for the naive question but I just bought a Kobo Glo as a gift for a person who has bad eyesight. I owned a Kindle Touch in the past so I know Amazon's devices elegantly display dictionary searches in a font size which is readable without the need of reading glasses. My priority when chosing the KOBO, though, was epub format support. The device is *almost* perfect for my friends needs apart from the font size in the dictionary lookup window which is to small. Is there any way (official or unofficial) to increase the font size?
