Consider adding an icon that lets the user know that a track has been rendered to Audio. Currently users are able to rendered to audio but there's no indication that a track has been rendered. Like a small icon. for example when there are layers in an audio clip, a little sandwich appears. Or when events have been grouped, you can see a chain link.
This is useful when users are working on large sessions and have to render audio to free up CPU.
Thank you, George.
