It would be great if folks could edit their check-ins. Similar to MP, you click a pencil-paper icon and an edit. Let's say you forgot to add some special personal notes on the run for next time. It would be very helpful to be able to go back in to your check-in and edit so you can easily recall it. A notes feature would also be nice to have. I've mentioned it for MP, but hasn't reached go-live yet.
