Grey bar in part cues

the grey bar indicates which cue (or part of it) will be effected for example by a Time command. and since the cue itself doesn't take timing instructions but the parts do, i feel it's the right behaviour to have the bar on one of the parts.
the golden pill around the cue (and part) numbers shows you it's active.

Thanks for clarifying the grey bar. Unfortunately the part with the grey bar also gets a central position on the screen. If you are in split screen, this could cause the next cue to become invisible. This way you cannot read the text of the upcoming cue. This could be solved by either putting the grey bar on the last cue part (which doesn't feel right after your explanation) or always display the upcoming cue, no matter how many cue parts the current cue might have.
