To the makers of Sigil -- thanks very much! Your program has been most helpful. I's like to report a small bug. An html file converted to epub 2 by Sigil (Windows version) lists all sections of the book with the extension htm in accord with the extension on the html file. However, when that epub file is converted to epub 3 using the epub3 plugin, the .htm extension is not converted to xhtml as it should be. This leaves the mildly time-consuming task of manually renaming the extensions. Of course, if the original html file is given an xtml extension instead of htm, then there is no problem.

This is a small matter but one that would be helpful to be fixed.

By the way, I could not find the referenced help documentation despite searching for it. Basic procedural matter like the above should be mentioned in the documentation, if not already.

Thanks again.
