Missing one important feature

I downloaded the preview version. I give only
4 stars for now and still postpone buying the
app. The contents from the book are there.
The images can be zoomed to see the detail.
There are audio and phonetic pronunciation,
but there is one important feature missing-
to change the font size. I will give 5 stars if
we can change the font size in different sizes.
