It is a general problem that manuals tend to tell you what "things" do not what "thing" you need at any given time. It is much easier to write them that way and, IMHO, the ZerOS manual is much better than most by this metric.
Knowing what "thing" you want is much harder. How does a writer cover the finite, but huge, array of possibilities without rivalling War And Peace? They can't, basically, and that is where training steps in. This forum also picks some of it up - how often do replies say "see the manual here"?
I have see very few of the training videos, my brain just doesn't like that input channel very much. So my take would be a separate "how to" guide giving you the workflow to plot a show (including how to add & correct cues) in one chapter, how to set up the desk for busking in another, etc. The history of questions posed on this forum should give an idea of other topics. Flowcharts could be a big part of it too. An online version could include links to the manual to get the details.
I'm waffling now. I'll leave it there.
