Please include the Response field in RE NXT/Events (webview)!  For "by invitation" events, all responses must be recorded. RE NXT/Events does not currently have the Response field, which is available in the Database view.  There is currently no easy way to track when an invitee indicates they will not be attending the event.  For my current events, I am having to go back and forth between webview and database view to track registration status.
