Set transparency of the Data Control lines linked to the RRG window

The RRG window is represented by a timeline in normal chart via the Data Control Link. The timelines sit on top of the bar and hide the wicks. When scanning through 10’s of charts having to move the Data Control time line sideways just to see the wicks is annoying. This request is to have an option to set the transparency - so the line is can still be visible - but does not hide the wicks of the most recent bar.
