Few quick thoughts:
* should have text in the airport field (both home and "location" if AOG) indicating "enter 4 digit identifier" so its clear should enter KRDD or RDD, for example
* on the current alerts screen, it would be great if there was a status indicator. Could it be tagged as "open", "resolved", "closed", etc.? That way a user can quickly see if the AOG alert has been addressed by somebody.
* are location services used, or planned to be used, for the app? When I push out an AOG alert from an airport identifier, does it go to anybody whose home field is within their user-specified radius of the AOG location? Or does it use their CURRENT location relative to the AOG location?
* when I click the alert, there is a "details" button upper RH corner of screen but does not appear to do anything
Thanks for the effort, impressive progress!
