I would recommand putting the map folder in the doc or creating an alias, as it is realy tedious to search in the package every time you want install a new map.
2.16 doesn't work right for me
at least two times now the shortcuts didn't function (i, e, r,d or x won't do anything) I'm on a 1.8G5 iMac with Mac OS X 10.3.8.
