As this is such a new feature, any feedback is appreciated. As kiwidude said - sample epubs allow us to check quickly and make changes if needed.
As I have said before, just talking to you guys helps.
Attached is the epub after removal of styles. Two styles:
font-family:Arial,"Times New Roman", Times, serif;
are not listed in the list of styles and are not removed.
