1. Saving FX settings as presets
2. Return to 0 on all knobs and sliders with a double click
3. Multi-region copy and paste option (ie, choose between bounce regions as it currently does vs replicate all regions)

These are all good features, unfortunately they won't make it in this next iteration. But at least the panning knob has a centering feature already. I'm predicting that AU's will be used extensively looking forward and they do support presets. MultiTrack will support AUv3 soon (the next update)
