Ok. So I summarize:

1. When kobo_extra.css is not present, plugin KoboTouchExtended produces a stylehacks.css file in the resulting kepub containing just:
   

   div#book-inner {
       margin-top: 0;
       margin-bottom: 0
       }

2. When kobo_extra.css is present, plugin KoboTouchExtended produces a stylehacks.css file in the resulting kepub containing:
   

   div#book-inner {
       margin-top: 0;
       margin-bottom: 0
       }
   body {
       margin: 0 !important;
       padding: 0 !important
       }
   body > div {
       padding-left: 0.2em !important;
       padding-right: 0.2em !important
       }

3. When I removed kobo_extra.css, the already created kepub remains with the correct settings and should normally display just fine as before. Perhaps I did recreated the kepub after the removal of kobo_extra.css.

My questions:

1. Where can the description for plugin KoboTouchExtended be found stating that this is the manner to use the plugin?
2. Are other settings possible for plugin KoboTouchExtended?
