This is good to hear. :) I wasn't sure if you wanted indents in your stories or the paragraph space but I've been doing some testing with converting the epubs to epub and I thought this css override code worked rather well.

body { margin: 0; }
a {text-decoration: none; color: black;}
a [href] {text-decoration: none; color: black;}
p {margin-top: 0pt; margin-bottom: 0pt; padding: 0pt; text-indent: 15pt; text-align: justify;}
h1 { text-align: center;}
h2 {text-align: center; }
h3 { text-align: center;}

I was going to make a post about. I'm not sure if you use Calibre to convert stories or not. But I think I'll be doing this.

I'm also happy that Calibre will now automatically convert smartquotes and em-dashes and ellipses to non-smart quote versions. :)
