Contents are displayed as a list.
The content labels can be modified by clicking on the pencil that appears when you hover the mouse over the label: this allows each content to be identified more precisely, without any impact on the content itself.
Images can also be displayed in a gallery.
A click on the preview of an image allows:
To edit an annotated image (in SVG format);
to preview the image and get additional information - especially the size which affects the size of your publications.
