I think I've found my own solution and perhaps it might work for you 'loungelyzard'...instead of having 8 registrations per folder make each folder 1 style registration with 8 variations. so when you click on the 2 registration buttons all the song titles are visible immediatley without the need to open up edit.
Gonna give this a go, if it does not work to well then I think I'll go for a Ketron SD1 instead.
