Add "File->Snapshot Stats" menu that copies the existing stats file into another file with date appended (or something) so people can easily save old stats.
Just as a reminder, users can export their stats files using "File->Export Stats Data" and "File->Export Location Data". They can also manually copy the raw stats files. This option is really just for safety sake.
