In older cubase versions, on an instrument track the inspector was divided in two colors : light grey for the general track tabs and dark grey for the vsti specific tabs, and it was way easier to differenciate them. Now they’re all light grey and i find myself spending more time on searching the tab i’m looking for.
This is part of the “god knows why” slight modifications inflicted to the gui, like the “divide track list” icon, that was on the left and suddenly appeared on the right, moving up and down when you click it…
