Sorry for the late reply and foremost, thank you for replying!
It looks like “propagate properties” does not do everything.
It does not propagate
• string indication placement
• line placement and length adaptation
• “many of the bending placements”
The last one seems odd, but corresponds exactly to my findings. Some of the bendings look fine, like I configured them in the partition, some of them look funny and need tweaking.
All in all there is still an awful lot to tweak. I am e.g. not able to place string indications beneath the staff by default, a practice I am used to since 40 years ago (I for my part haven’t seen guitar literature yet where strings are indicated next to the note).
I do sincerely hope the next iteration of Dorico has something under the hood to speed up the guitar player’s workflow, like the afore-mentioned string indication placement, semantic position marking, semantic fingering (semantic = adjusting strings being used for given notes in a given position / adjusting fingering and strings based on fingering-string-combination or position marking already created for previous notes) and easy and versatile barré creation. I love the output! But I wish I could be quicker…
