I came from using Premiere elements and in the project panel, when a media item was used in the time line, a check mark would be placed beside the item showing that it has been used. I can't seem to find in Pro where it shows that I have used my source in the time line. This is frustrating because I have a long project and I keep having to go over and over the media to make sure I either, haven't used something twice or that I haven't missed anything. This is very time consuming. I think I am just overlooking it. Any suggestions.
