The following behavior is a major annoyance IMHO:
New > Empty Project
VST Instruments > Add any instrument (say Spector)
Choose to “Create” MIDI track when prompted
Collapse the “VST Instruments” folder in the track list
Select the MIDI track
In the Inspector, open the Audio Fader section
Click the “e” button to open the Channel Settings window
The MIDI track gets deselected. Moreover, if you now close the Channel Setting window, it’s impossible to bring it back from the MIDI track. You have to do it in the Mixer.
Also, the Audio Fader is the only section in the Inspector for which there is no Toggle Key Command available. I think this should be fixed, too.
