Two very small feature requests:

When saving a tracking to file, if the file exists it does not warn you that it is going to over write the existing file. (I just happened to over write yesterday's tracking. This time it was not important, but it could have been)

When you have enabled tracking it is probably because you want to log where you have been, but you can easily close Mapper by mistake and it does not prompt you that you have tracking enabled and it will stop tracking if you close Mapper.

These are just two house keeping features, but it will really make Mapper more robust.
