First I love C9, so here is a minor thing that would make it even better.
I’m using all 3 mixers and when the project opens they are opened in the wrong order which is annoying as you are
used to layout. So if you save the project with mixers opened as 1, 2, 3 and they re-open as 3, 2, 1 or 2,1,3 all other permutations you have to close 3 and 2 and reopen them every time.
I know a small thing but still annoying.
