In multitrack mode, when punching over clips the clips are stacked on top of each other, hiding previous takes, which makes trimming awkward because previous takes are exposed (thus unmuting them) during trimming.

It would be nice if Adobe would place punched segments on an sub track below the original and mute the inactive (replaced) clips to make trims more efficient. The resultant punches should be grouped by default to the original clip so that they will automatically follow shifts in time.
