Sometimes in the mix view it’s difficult to navigate the project.
If I want to loop a perticular section I usually have to go back to the project window and set it up.
Then back again to change it.
What about something like the timeline at the top of the mixer?
Perhaps put a waveform representation of the master output in the background so you can see where everything is.
So you can click and instantly go to any spot or set loops exactly where you want.
Just a suggestion.
