I'm using Premiere 24.6.0 currently, so please forgive me if this was already implimented in version 25.
In the Marker Panel, the In and Out points of all markers are shown, but not the Duration of the markers.
For me, it would be extremely helpful if Duration was shown. I use the Duration of markers often because I use markers to lay out where my graphics will go and how long they should be on screen. As it is, the only way to see the Duration is to mouse over the marker itself in the timeline. Having Duration in the Marker Panel would be a huge time-saver!
Thanks, and have a great day!
