I use PaperUI/HabMin on 2.5.0-SNAPSHOT (#1650) on openhabian pi.
I want to use the out-of-the-box functionality for adding things and their items, so to speak simple mode. After creating the items I would like to group them. So I turn off simple mode and try to edit the group attribute for the items.
