This is a great list. I just wish I could choose more than one item. My favorites (in order) are: audio input, sample and hold, note off for sequencer, inverter for waveforms, one screen synth window, Schmitt trigger (if I have audio input, an envelope follower is essential)
I could be wrong but I thought some of these features were already locked in to a future version, such as sample and hold and inverted waves. (?)
