@JSWolf, that is a great idea. Thanks!. Jackie_w, thanks for the link.
Actually, I could bear to part with the dropcaps, so that is not my main concern. What I am really worried about is the font size rescaling. I do not yet understand it fully and I am not sure whether to leave it on or disabled, and I don't know the "ideal" font sizes to use for AZW3. I tried enabling and disabling font size rescaling and both options proved unsatisfactory. I could not get the proper font sizes that would look good on the kindle.
