On Mac at least, it's not so hot to store application data in $HOME
directly. Certainly also on other platforms there are better places
to store this. Can I suggest, on Mac at least, to move the data files
into ~/Library/Application Support/dowser/<blah> ? The relevant
lines are in db.py, db_sqllite.py and utils.py.
There's a similar folder on Windows, and perhaps linux bods might
Good work tho!
