Excel has long had a very handy feature by which you could make certain rows non-scrolling, such that they are always visible, even when you scroll to higher-numbered rows. This would be extremely useful in Cubase, too. For example, I’d love to have a Marker track always visible, regardless of what track I’m working on. (I’d also like to have it in the Sample and MIDI editors, too, but that’s another topic.)
But I can see it useful for most any type of track, e.g., a vocal track, drum track, etc. - anything you might need as a reference for other tracks.
The workaround now is to manually drag the reference track further down the list of tracks, as needed, and then put it back where it’s supposed to be.
