dividers between dialogue, sound effects, and music tracks
As an Assistant Editor, in Avid, I'll sometimes turn on some tracks (the ones that show timeline duration in 24fps, 25fps, etc.) and use them as "dividers" so I can easily see which tracks are my music tracks, which ones my sound effects should be on, etc. This would be useful in Premiere. The "dividers" should only be as a reference (people should be able to move clips over or under them). It's just helpful, when doing music cue sheets and stems for composers, to easily see, "Oh, there's a music clip that's on the wrong track," "There's a sound effect on the wrong track," etc. In docuseries, I even have to put diagetic archival sound on separate tracks (so I can export an EDL in order to make a music cue sheet).
As a workaround, I've locked the top track in my diagetic tracks, and the top track in my music tracks; but I have to unlock them if I have to move something out of them.
