Reference line over all tracks

When I try to align multiple (vocal) tracks I like to see if they all align well. I can use my cursor as a vertical line, But on the moment I see that one track needs some warp and I click that track, the cursor jumps to my mouse position, away is the reference.
Also after a play action the reference line is gone as well.
Is there a way to draw a vertical line over all tracks?
The only workaround is to precicely click on the cursor position when selecting another track. As this multi track alignment is a lot of work and a lot of clicks I miss the cursor line too often.

Things I already tried:
The (purple) range selector is not showing over the tracks: not usable
A marker is only showing in the marker track: not usable.

Make more use of the bar / beat gridlines? Set the quantise level to 16ths for example and you’ll get much finer bar / beat gridlines.

You can make the gridlines more prominent in the preferences.

There is a setting within the click track that can also effect what bar / beat gridlines are shown as well.

Thanks, that will do.
Grid needs to be on ‘Use Quantize’
Gridline intensity: Edit>Prefs>Event Display>Grid overlay intensity

You can change that in the Preferences:

That should give you graphical guidelines. At least in the project. The guides are not visible in the Sample Editor.
