I've been working on an issue that has demanded incremental changes in an attempt to understand both the documentation and peripheral.

I've found that I would really like to be able to do two things with the historical waveforms:

1. Pin a Waveform.
   This would allow us to make a capture and keep it in the history - currently old waveforms will be discarded to maintain the configured maximum. Behind the scenes, this could be implemented as a separate queue, or it could be implemented by allowing "pinned" waveforms to bubble to the top and then persist. I'm happy (and able) to configure quite a large history (>100 wfms), so I'm okay with the latter, but others may prefer the former.
2. Label / Name a Waveform.
   In the workflow I've outlined, this would permit a textual name to be associated with the waveform. For example, register values that produced the given waveform. The timestamp is still useful, so I'd suggest presenting this along-side the timestamp.

I've included a nasty mockup below:
