I think it could be extremely useful if the track name could dynamically change to the region/event name while it was under the cursor during play back. this feature could either be on all the time by preference, or perhaps a key command toggle like most other preferences.
say for example, shared group of fx tracks that contain layers of hits and impacts. It would be great if while that section is playing, my Mackie or Avid display would update and switch from Fx A, Fx B and Fx C… to GLASS BRK, WOODBRK and RUBBLE. I can quickly see what is what and the names can just be part of my editing workflow that facilitates and smooth and flexible mix!
