This was first brought up by Mike McCue in another section of the forum, but I don't know that it was ever an official "feature request", so here it is: a feature where you can select a range on the timeline and there is a read out in SONAR that tells you how long the selection is in H:M:S:F.
 
This would be very handy for those of us who use Sonar to produce advertising jingles. My typical 60-second donut begins with a few seconds of intro for announcer talk time, followed by the jingle sing, a bed for the main commercial voice-over, an end jingle sing, and then a short instrumental stinger to provide for the business address or whatever at the very end. 
 
Advertising copywriters prepare copy that needs to fit exactly in the instrumental sections of the jingle, so I need to let them know how many seconds each section provides. Being able to select the various ranges in the timeline would make this a very easy task.
