The envelope clips would have functions like looping (just like groove clips), reverse, invert, drag-stretch, scale, and that funky warping thing Studio One has. It would allow quick copying of envelopes without having to use copy paste. Could also be duplicated of course, once duplicate is implemented, which I trust is at the next update. Right? There would also be integrated envelope sidechaining in each automation lane, to modulate an envelope with another (lanes inside lanes with an automatable crossfade, basically). In addition, there would be a way to select an automation range directly in the automation lane, without having to set a macro control in the effect or instrument.
Oh. Needless to say, this would be a great occasion to implement freely curvable automation segments.
