Hey, no problem, it makes sense. File::Settings:: can change both the locale and the time zone. That should be the responsibility of whoever wants to make a copy to edit.
I also tried a trick with my local copy. I wrote a function in the English locale then converted to Spanish. It turns out
=countif(c3:c21,"x")
which works in English locale doesn't work, but
=countif(c3:c21;"x")
which it's converted to, works in the Spanish locale. Grammar police, eh?
