Increase visibility of dividing line between Video and Audio layers
Increase the overall brightness of the dividing line between video and audio layers in order to make the separation between V1 and A1 easier to see across the entire timeline.

In agreement and support of increasing the visibility of the Video/Audio dividing line. Had a similar (but different) idea to make the division between the video area and audio area of a sequence more clear for faster user processing/differentiating. What if there were an appearance option to change the background color/brightness of the video or audio area of a sequence. Mocked up this idea in the attached image.
