You can customize it by copying the default jacket template directory to your personal resources dir and then editing the files. The manual page explains it, but it may be a little out of date as for me the source dir is C:\Program Files\Calibre2\app\resources\jacket . Custom columns can be added by using _ instead of #. For #genre:

        <div>
          <p class="cbj_label">{_genre_label}:</p>
          <p class="cbj_content">{_genre}</p>
        </div>

FFF on update will discard the jacket file. But FFF already has an option to invoke the Polish option to smarten punctuation and I would be willing to add a similar option to automatically call Polish update jacket.

UPDATE: Calling Polish to update jacket might be more difficult than that--there are some 'interesting' interactions between conversion and jacket I would need to explore more.

(BTW, note that if you use Polish to add/update cover page, it will name the cover page file titlepage.xhtml. FFF's title page (title_page.xhtml) is unchanged.)

Thanks JimmXinu and ilovejedd, I tried polish but it gives me a whole extra page that I don´t need – nor want.
It also copies my epub in “Original-EPUB” and adds the new title page in “EPUB” – which makes two EPUBs for which I need memory space when I want only one epub.

It´s only one maybe two of my custom columns that I want to add.
I liked the existing option to add columns to the “normal” title page. And all columns that are filled by settings in personal.ini already work when downloading.
It is just the hassle with columns that are manually filled after downloading.
