I think that human intervention will always be required to produce the best result in music engraving no matter how excellent the computer program used because engraving rules alone are not sufficient to deal with the complexity of musical notation—and for that reason, human intervention should be facilitated, not made more difficult.While having more finished features (especially from the "basic" category) would certainly be preferable, I think that a simple note-offset available right now would probably just lead to fewer users unlocking the true power of Dorico, which comes much more from a deeply ingrained understanding of notation than on any approach of just moving graphics around.
For example, in the last few measures from the Bach 6-voice Ricercare shown in your article, Dorico made many errors that you corrected. Your final result was much improved, aside from a few quarter rests that are very close to the note heads in bars 3-5 and the two side-by-side half-notes in measure 3 that might better be a single double-stemmed one, as in the composer's MS and the New Bach Edition. The composer's MS also has superior distribution of the notes between the staves (and hands) in these measures, and the whole piece is in a subdivided 4/2 rather than 2/2. http://petrucci.mus.auth.gr/imglnks/usi ... ikel_1.pdf
