Yeah it just seemed really weird/surprising to me (in the sense of 'principle of least surprise') to put that in scripts/ and it doesn't seem that traditionally anything else like this lives there. But if you guys feel strongly enough I can put it there. And agreed probably a 'third place' is the right way, but probably not right as part of this series :) > > -- > Cheers, > Nathan -- Cheers, Lorenzo
