It would be great to also see the class IDs in “Classes” section:
I have also noticed that the labels are sorted by name. I needed to rename my labels, and this switched my order in the classes. This is a bad feature from my pov - when changing a class name, the class should by mapped to the same id as before.
Please also provide an option to export the class labels and IDs as csv (there is an import option, but no export option - in case you need to revert something)
