Yep... and the trouble is, every publisher may consider some
other font size "normal". It's impossible for Marvin to predict any of that before it even opens the book.
Luckily, we have all those handy formatting buttons in Marvin, and once you set a book's font size (and other typesetting options) to what is comfortable for
you, it will remain
sticky forever for you in
that particular book. That's one of Marvin's greatest features, and one that I haven't seen in
any other e-reader so far! (Not even in Stanza, the original inspiration for Marvin; if you increased the font size in Stanza in
one book, Stanza would at the same time increase it in
all books, which frequently caused problems.)
Naturally, the best practice for publishers is not to set
any specific font sizes in their e-books, other than
relative sizes of the
2em variety. Are e-book publishers (especially amateurs, but not only them) this reasonable? Of course not...
