I figured out that using <% story id="..." %> you can easily make editable boxes in your template for linklists, desktop wallpapers, current readings etc. Here is little explanation in German. It only works because I'm using the story.display skin in a way it is not intended. A nicer solution would be an additional skin, say story.include.

It's just a new skin and tiny modifications in the skin manager (additional field) and the <% story %> macro (new default value for the skin). If you agree I can make the changes.
