Thanks for the post! This is the first time I've personally seen a situation where the globals actually fit the use! Cool.
Globals are personal things...they are actually Global per person so I don't think you'll have an issue.
Most of the posts I've read here on the forum desire "global globals" which don't exist on FMP (yet?). The "personal globals" seem to be exactly what you want...and that is what FMP globals are.
