I like the look of the new ArcGIS Web Editor that was released this week for ArcGIS Online. But it does raise the question of why add this functionality to another new application rather than simply extend the editing functionality that already exists in Map Viewer. I'm baffled by the continual development of new products that perform subtly different tasks from existing products (Quick Capture, Field Maps, and Survey 123; Experience Builder and Dashboards). Surely a better approach would be to consolidate and enhance the functionality in a single application? In the case of Web Editor, it does seem like this functionality could have been integrated in to Map Viewer.
Just my thoughts.
