Everything works fine, including ToC and special characters (german Umlaute).
I noticed two things though;
My text is all Arial, but the exported epub is in a serif font as I can see in Calibres epub viewer. I made a reference epub using the Atlantis trial, which displays in the Arial font used in the viewer. (my reader seems to only display serif in both files anyway, so this point is somewhat academic).
The second point is the orientation in tables seems to get lost or reset to left, even though it's "centered" in writer.
Hint: Getting rid of page margins helps greatly in the appearance of the text on the reader.
THANK YOU VERY MUCH, THIS IS AWESOME AND EASY!!!
