I'd also vote for ability to delete unwanted processing modes ... there are many I don't use, and cycling between them is a pain for my Wife on a Crestron

It'd also be nice to change crossover slopes, even better independently on both the sub and speakers themselves (that way I could do 12db octave on the mains, which added to their existing 12db natural roll off would be 24, and then dial in the subs coming in at 24. I can dream can't I?)
