Viewer Annotation cards

### Viewer Design

**Here are suggestions for the viewer side bar and the viewer cards:**

Here you can see the sidebar where the annotations are listed. On top there is an infobox about the default annotations, then you can see the preview for the first annotation, the title and the annotation itself (here only a description for the first annotation). The annotations are separated with a grey line.

The card for the annotations could look like this:
Either only text or text and media.

You have icons to make the annotation bigger. That could look like here for example. The background could become more transparent or darker then.

And you have an icon to edit or delete an annotation.

Edit:
Here we should discuss how exactly media is embedded. With a link? How to add several media types?
