Yes! I'd like to encourage a little exploring and making the student
think instead of exactly telling every move to make click by click. But
no so abstract that they get lost. If you are told to pick the "elevation"
map but are only presented with "elevation.dem" and "elevation.10m", both
of which work fine, I'd argue that it's healthy to make them make a
personal choice, they get more personal reward from it that way (sort
of like telling them to select their home-town from a global dataset).
[ok, I'm reaching out on the limb :)]


> Sorry for the provocation, but that is the status quo.

No need to apologize, we get a better end result from frank but courteous
discussion.

I do take your point, and I've now reworded it slightly to give the
exact map names at the start and make it more like "click on your elevation
map" instead of "click on the `elevation` map".

it is positive feedback indeed, and that's critical (especially in the
first 5 minutes of the tutorial when they are very unsure of what they're
doing), but again I wouldn't mind a little deviations and choose your
own adventure to it. (both ways visually look fine, and fwiw I'd say the
smaller threshold size has a better looking v.colors result)
Or you can read that as the payoff:effort ratio for me to cut a new
screenshot has not yet exceeded 1.0.

I'm much more concerned about the time they'll spend in the menus and
tabs trying to find first the r.watershed module and then the threshold
option. I know it well and where it is, and still I have to hunt for it.
Lots of screenshots with menu entries circled in red with arrows and things
would be great (Markus N did one like that for the startup screen help
page), but is beyond the scope of this quickstart which is already a bit
on the large side for what it's supposed to be.

Done, but I left off the @PERMANENT part, those are the only maps to
choose from at that point so you can't go wrong & it just clutters the
text.
