As far as I remember another discussion the paragraph IDs will change if
you export/import or copy a notebook (not sure which one applies). If that is
the case the workflow will be broken after import. If the user in front of the
screen is not familiar with the code and logic of the notebook, it might be
difficult to fix.
What about a simple "z.wait(ordernumber or paragraphId)" function which
makes the paragraph wait for the paragraph referenced by the ordernumber or id
to finish successfully or cancel the paragraph execution in case of an error?
This way all paragraphs without z.wait will be executed in parallel and
those calling z.wait would be executed in sequence to the ones they depend on.
And additionally this kind of functionality would not be mixed with the job
handling on notebook level.
