Would it be possible to add a drag and drop here to rearrange the items?
This would make so much sense to keep the overview when you add items at a later point for example.
I think I already read it somewhere, but not sure. So here another suggestion:
Ability to copy/paste existing items inside the Relative Styling list.
I love to use this feature because it brings the possibilities to another level. So my suggestions are already workflow related, the core is a dream already!
