The subject hierarchy should be clearer

[MarHerUMR]

In the subject drop down you have the subjects sorted as the Destatis-Systematik der Fächergruppen, Studienbereiche und Studienfächer. It looks like that the elements on the second level of the hierarchy are slightly indented. I think the interface would improve if you could give an indication on which level every element is. Especially if you scrolled a bit down I find it hard to identify the levels of items.

Thanks for the report. You are definitely right that the UI could be clearer here. We will take care of this.
@literarymachine, I suggest to increase indentation and add vertical lines for orientation as in https://w3id.org/class/hochschulfaechersystematik/scheme#.

The extension actually only wraps https://skohub.io/editor/, so styles should be fixed here.
