It would be helpful if you could add a popup when the user presses Stop when logging. The popup should ask if you want to save now. If yes, allow to save and stop logging. If no, do nothing.
I don't log often enough to remember to hit Edit in order to save the log... this is just not intuitive. I have lost several logs because of this and get pretty frustrated after spending time doing WOTs and other things that the local law enforcement may frown on... but need to do in order to get an updated log.
Just a thought on improving the UI and customer experience...
Thanks,
Mike
