A nice addition for an update to Supernova 2 would be a (Mac Book Pro) laptop control scheme. The plus and minus buttons do not work for a laptop (it has no number pad). Kind of hard to control real time turns without the plus and minus buttons. Also trackpad seems kind of eradicate on my mac book pro laptop too.
Try using the function key "fn" with the + and - keys to change the speed. It works on my PowerBook G4. This saves the hassle of turning the imbedded keypad on and off all the time. Plus I think the "p" key is more intuitive for the pause function than the "0" key.
