It would be great that Lower zone gives only these Tabs, which are relevant for selection. In other words - hide Tab, if there is nothing to show. For example, if I select Audio or Sampler track, you can hide Editor yab. Check other relevance if it’s there, but since I request for QuickControls in Lower zone (some minutes ago), then it also can be shown only for Instrument track. For Arranger track there can be shown whole arranged song - clickable as part map or smth. like that.
