Please oh please,
An option in the Preferences:
Channel settings (“e” edit button) on a midi track shows audio output (if it is connected to a VSTi)
Right now, only the first channel of a Track Instrument supports this. Other than that you get to see midi inserts/sends, midi volume and pan on the editor. Most people never use midi inserts/sends anyway. But they DO use audio output of that midi channel.
If it is an option in Preferences, everyone will be happy.
Edit: Especially useful when the ch. settings windows is left open and following your track selection.
