I would love to see the ability to change a field name in Pro's Catalog Pane or Catalog View without having to export out the attribute rules, make the field name change, and then re-import the rules and manually have to fix any Arcade references using the old field name. I realize it's best to just be sure of your field naming conventions prior to building your attribute rules, however, mistakes and changes do occur sometimes and this would be a big time saver.
