yeah it can suck up your time, but i just love doing that sort of thing.
my file manager (Directory Opus) is similar. not so much scripting, but you can customize/tweak everything you see. it took me months to get it just right!
anyway happy i could help. i learned what i know off of other people, so there's a great big chain of foobar script sharing that must stretch all the way around the world. i love the internet
