+1 Here… MIDI needs to be improved for sure… Especially the Score Editing part…
I can give you as an example the Pro Tools, after the implementation of Sibelius into the DAW… They now have ready for printing scores, not notes which look 8 bit graphic.
Another point is to make Cubase 8 + to be able to work properly only with writing scores. There are people who would prefer to use the Score Editor for composing instead of Piano Roll.
Yeah, I know that Steinberg is going to release new Notation program which would change the market, but anyway, I would prefer to have well engraved scores and to use the Score Editor as functional as the Piano Roll…
Even it would be great if I’m able to create normal Symphonic Orchestra score sheets…
If there is opportunity to change the positions of the midi tracks in Project Editor, by editing them in the Score Editor, it would be awesome, too… 
I have more ideas about the functionality of the Score Editor, but I don’t have any hope someone from Steinberg to pay attention on them…
P.S:
Another of my requests related to the score editing you would find here:
