It would be handy when mixing, to hear immediate results of dragging an automation line. Currently you have to release the mouse to hear how for example a volume envelope will sound, if you're dragging a dot or the line between the two dots. Would be so much easier to hear it already while dragging.
Especially when you can't even see the current or new values of each ends of the automation curve, so you don't know how much you're actually changing.
