The one place for your designs

I would prefer to have all edit options in one place (that would be the curation part of the MP). Therefore I argue, that there are better options as the current one to edit such static pages. It could be served from the database via the API or - as Stefan proposes - there are markdown files that can be edited and that are read by the frontend. There are sure some other options on this.
It has no high priority, but we should keep it in mind. If the about page is the only static page we need, then we may leave it this way, but if there are more "static" information pages planned to integrate on the MP, we should discuss the best option.
