Feature: selection of the display label, e.g. "prefLabel"

Thanks for developing this useful tool !
I was trying to visualise the EMMO ontology.
They use UUIDs as their class names out of good reason, but also defined "SKOS:prefLabel" for human readability.

It would be nice, if EVONNE would support switching the view representation also to "prefLabel" (e..g. in the settings module).
Thanks.
