See attached piccie. I simply want an optional (with a keycommand to instantly enable/disable) translucent vertical rule to extend downward from each Marker to the bottom of the project (as one can do in Microsoft Excel) so that I can more easily see what bar/beat the marker is indicating. On a large CPR with lots of tracks this gets to be a real challenge.
Each rule would match the colour of its marker, just be translucent.
