Here's why I need to drop out: while you've *written* a few thousand lines of FXRuby, I've only *copied* a few thousand lines of Ruby from; -- samples in the Ruby installation -- books: yours, Matz', Thomas et al's, Feldt et al's. -- answers posted to questions on Ruby-Users & FXRuby-Users. I've got most of them running, sometimes with modified to explicate their functionality or to provide minor enhancements. But there are still a slew of Ruby and FXRuby features I want to investigate. So I'm still to uninformed to weigh in on serious enhancements such as yours.
