Oh gosh, how absurd! I typed all my comments (feedback in Esri lingo) in the previous field because there was no place to give feedback. Please email me about where the feedback should go, because this is very frustrating when it should be easy. Key point to remember: I'm not asking a question or searching for answers--I'm trying to leave "feedback" about the new beta Map Viewer. I worked with it for a while and have many suggestions to make it work intuitively instead of annoying the user.
