I’m getting into Dorico right now. How gratifying not to be welcomed by the usual 4/4 rhythm grid!
There are a couple things I would find nice for speeding entry.
a) Consolidate the Write > Create commands under a single Write > Create sub-menu. Having the “Create” word repeating is a bit clumsy, and makes the Write menu too long (and unbalanced compared to the other menus).
b) Have a different context-sensitive menu, depending on the current selection. If nothing is selected, the Create contextual menu could appear, and allow for creating something new. If something is selected, the Edit contextual menu could appear, with commands useful for the selected item.
Keep going the great work!
