Diagram / Element details
Diagram or element details are listed in the Properties panel, which by default is to the right of the diagram window.
If the panel is closed, you can open it by clicking on the "Properties" button in the Diagram menu.
The details listed include the description, responsibilities, extended attributes and tags of the diagram or selected element, as far as they have been maintained.
If you select an element, its color changes to green. This way you can differentiate whether you are looking at the details of the diagram or an element and which one it is.
In the breadcrumb bar at the bottom left of the diagram window you can see the folder path of your open diagram.
If views are maintained, the view options are displayed at the end of this bar / folder path. You can switch between the views by clicking on the name of the desired view.
