Currently, we're showing all audio tracks by name only, including tracks that are disabled.
- We should be removing disabled tracks from the selection list.
- Show "Name [disabled]" for tracks that were previously selected but are now disabled.
- Indicate the Scene name of the track if it is associated with a layer or
- Indicate the track as global if marked global or is an Input audio track.
note(meach): this requires upstream changes to Meld's webchannel API to send each track's Audio track enabled/global flags.
