Dorico is extremely well thought out. The basis is very much there and you can already do a lot. Here are some of my wishlist feature request for the next updates (mostly using Dorico in a Filmmusic / larger orchestral and big band score). I am sure most of them are known by the dev. team. Nevertheless, here are my observation for my personal needs and my order of priority. Most of them would be really necessary to use Dorico for me in a project with tight deadlines professionally:
(D1.2) No Coloured Key Ranges
(D1.2 ) Help - a Search Menu (Similar to Sib on Mac & PC)
(D1.2) Transform Plugin: Sharps as Flats / Flats as Sharps (( Workaround Filtertering sharps and flats and enharmonic transposing are still two steps))
(D1.2) Duplicate (Copy-Paste Part) Layouts missing
(D1.2) Harp Pedalling Missing
(D1.2) Focus on Staves ((Workaround - Create Custom Layouts from Full Score: Feature Request - More view options in Gallery View -))
(D1.2) Show Hide Text in Score / Parts
(D1.2) Arrangement Plugins Missing / Explode feature etc.
(D1.2) Optimise Staff Spacing (To Avoid Collisions even better automatically, although its doing a good job)
(D1.2) Multiple Players per Staff in Full Score Missing
(D1.2) Better Internal Sounds (wallender sounds integration ?)
(D1.2) Divisi Staff Missing: Divisi Strings on separate staves
(D1.2) Gallery View: No way to engrave (optimise staff spacing or drag staff etc.) in order to avoid collision between dynamics, playing styles etc…
(D1.2) Gallery View: Please give us the option to not display any multi rests when in gallery view.
(D1.2) Horn in F Bass Clef wrong transposition: Horn in F - Bass clef - Dorico does not know right transposition
(D1.2) View Bar numbers in Gallery View also over the Strings Section (very useful for large scores in arranging film music scores)
(D1.2) Show Bar number under Multi Rests
(D1.2) No batch processing for creating single Parts Title Pages
(D1.2) Dorico can not show the different players for different flows (Even though in my ensemble “Player One” can play Flute & Alto Flute, Dorico can not show in the individual part score that Flow 1 only uses Flute 1 (in the part name) and Flow 2 uses both instruments for the same player in the part name.
(D1.2) No Cubase Integration yet
