a.) It doesn't show in ADE. I can access the SD card though, it's not a windows/driver problem.
b.) Might be directly related with a.): When reading, I don't see the book covers on the LCD screen. I've only got the symbol (ePUB, PDF, ...) but not the book cover like the user guide shows.
c.) In ePUBs you can change the font size, but in PDFs I can't? Wouldn't have expected that. I can zoom into the LCD, but I can't change the font on the actual reading area?
EDIT: Thanks to the support of Spring Design,
problem b.) is solved:
