Thank you for your kind iTunes App Store reviews. Please keep them coming. You'll see a number of improvements in the next version of PotholeSnitch.
One commenter suggested that tagged points do not persist if one exits the app before reporting them. I have considered this issue. Unfortunately, simple persistence may not be a satisfactory solution for all users. If one drives some distance from the original tagged points, the old points' reports will be lumped together with new points, possibly in a different municipal authority area. That may not be what you intended. In any case, I'll try to address this issue in a future version of the Snitch.
In the meantime, here's a workaround:
1) Before exiting the Snitch, enter "Report!"
2) Edit the email by typing something - anything - in the message body. A space is sufficient.
3) Press the Cancel button.
4) You will be prompted with a Save/Don't Save/Cancel dialogue. Choose Save.
This approach will save your email in the drafts folder, and in essence, your points are saved. You can enter your email account and forward the message from your drafts folder at a later time. Note that when you cancel a message, your tagged points are not erased from the map when the email page is dismissed, so be aware that you may send duplicate reports.
I am reading your comments and am always open to enhancement requests.
