The trigger facility is great for finding events such as anomalous pulses. If these events were shown as a virtual data channel it would allow the measurement tool to be used to easily characterize patterns of events. At present this can be done by manually noting when events happen or by using timing marker pairs to measure times between events, but it is hard to get a quick overview that way.
A very powerful version of this idea would allow channels to be added with their own trigger expressions drawing on data in other channels. (As a software engineer my eyes start to glow with the possibilities for scripted event matching algorithms.)
