I waste a lot of time trying to get panning automation to be ‘C’ when drawing automation lines on tracks where the size of the automation lane is the default size.
Having to resize the lane to zoom in to a certain magical level and then slowly moving it until it gets right between L1 R1 is annoying.
At any zoom level, you should be able to snap to C for automation. Same goes for 0 for volume or indeed, any resetting value for any automation lane.
