Emailing coordinates before deleting
I went to download my locations and found it only saved back 16 pages. With unlimited tracing this did not go far back in my holiday so I have lost much of the trip info.
My idea is to save say 110 locations in a buffer and when the buffer is full email the the oldest 100 locations to the user and then delete the buffer. That way you do not need to save locations and the user will get all locations to do with what they like. One format is good enough as if you are using them then you will be able to convert between formats.
