[JW Lua] More class questions

Fri Aug 30 19:42:42 CEST 2013

So am I watching ... a programmer and arranger from Germany.
I have worked on some Finale scripts in the past, but that's really
uncomfortable programming and most ideas are not even possible.

This will be a fantastic thing for Finale !
Thanks for all your great contributions, Jari.
