If the software interface ever gets any sort of substantial update:
Rescalabitlity - it's darn hard to read, people have bigger monitors now, so a scalable interface is crucial (I know about other ways of doing this, but that shouldn't be necessary).
When moving/assembling patch libs, often, I have a new patch that I'd like to stick at the front of my list, but right now, it seems I can only paste over a different one, which is a real hassle. It'd be nice to have the option of pasting a new patch in between other ones.
