Also:

• [x] Display better mapping name. currently, the editable mapping only has an ID as a name. it would be cool to see the name of the mapping which this is based on. probably also requires backend changes? [edit by @fm3 : the backend changes are included in https://github.com/scalableminds/webknossos/pull/6446 ]
