Regarding number 2, I’m genuinely curious what some of those things are.
I’m one of those who have posted such suggestions earlier, and don’t like to repeat myself too much. But the answer is simply: Anything that can be done with a mouse should be doable with a mouse, and the same goes for contextual menus, and key commands. (And menus.) One example I have mentioned earlier, from the top of my head: If we want a bar in the middle of a system to become the first bar in the next system, the easiest way would be to simply drag it to where you want it.
And if you are used to working with programs that have proper implementation of contextual menus everywhere, you already know that this is a massive time saver. For instance, whatever you want to do with a note/note head should be doable by right-clicking or control-clicking on that note/note head. Whatever you want to do with a rest (eg remove/hide it): same thing. Want to change treble clef into alto clef? Choose alto clef from a contexual menu. Want to add a nnote at any random position? Same thing. Want to increase the distance between treble and bass clef in a piano score? Grab any of the clefs and drag up or down. Want to insert a time signatur eat any given position? Contextual menu. Same for time signature change. Want to rename a text? Double-click on it.
Dorico already has many great mouse functions, and I’m sure more will come.
But for all of us who are either in…
checking-out-Dorico mode or
can’t-use-Dorico-yet mode, or
still compose in another app and only use Dorico occasionally, or
or are over 60 and already have the head full of key commands from other programs, or
plan to actively keep using multiple programs in parallel for a while, or
have written many software reviews and have become rather stubborn about what the easiest possible UI solutions for complex apps consist of…
(I’m in all those categories, btw!)
…a more obvious UI is IMHO even more important than some of the features I miss the most. Except real time MIDI recording from an external MIDI keyboard, which is way faster than using key commands. It also allows entering of pitch, length and velocity with only one keyboard click - which, to me, is a more musical way to do enter music than having to do it with a computer keyboard.
