That's a great and swift response Jasper. I hope this proves to be true. After all this was requested a year ago and nothing happened.
So I'll keep my fingers crossed that this did really slip through the net last year, and now happens.
I'm glad you agree that subgroups are rather pointless unless you can apply the same functionality as the main groups. It's totally in your own interest to harmonise this functionality.
Thanks and good luck.
