I don't quite understand why should rename all my fields in "user readable" format. What is the use of labels for then? 🙂
I also was expecting to have the label shown as part of the current selection. I even tried by using a Master Dimension, but it still shows the field name. There are plenty of reasons why I would use a different label for the same field depending on the context, so yeah, it's quite disappointing to see that this is not supported.
