Anxious to see a feature editor widget added to Experience Builder to gain parity with WAB. Have done some workarounds with Survey123, but they are clunky, labor intensive on the back end, and work best for existing features. Ideally, a new editor widget similar to the "Smart Editor" but with a more user friendly interface (read: BIG, customizable buttons built from feature templates and/or subtypes) is added to Experience Builder. Something that not only allows for the editing of existing features but for streamlined creation of new features and a form-based/popup-based interface for user attribute input. Perhaps it could receive input from map widgets (e.g. location), and be triggered by other widgets (e.g. buttons).
This would expand the utility of Experience Builder in a huge way.
