Found this question and am cross posting to make it an idea. The change to Sidebar from listing multiple results as a list to the pop-up style 1 of X menu defeats one of the main advantages of the Sidebar app, which was that it made it superior to other apps.
In our many years of making public-facing ArcGIS Online apps, time and time again we've had to field the question of people not seeing that there are multiple pop-ups when they click on overlapping features. No one ever looks for the pop-up 1 of X menu on their own. When we use Sidebar and have the results as a list, we never get questions because people inherently understand the results.
Please revert Sidebar back to the superior and web-standard method of listing multiple results as a list. Classic Panel is best panel and should not be replaced.
