Rename Fields

Is there any way to rename a field? If not, could this be a feature request or is it technically impossible?
Thanks a lot,
Stefan

@s4a it looks like a bug, something that I missed, right now I can’t think of any technical showstopper that would prevent me to implement the renaming of fields. I’ll look into that when I’m back from vacations, in the second half of August.

Thank you so much!
