Hello. I ask the creators of Vegas Pro to include a simple but very useful thing for us, in the explorer sign somehow, like a dot, a green comma, etc., on the icon of the file that is added to the time line, and at the moment of deleting it from the time line, that signature should be deleted, so that we know which file we used and which one we didn't. Working with many video files is very difficult in Vegas because of this. I've been waiting for this improvement for over 10 years, since I've been working with Vegas Pro, I've bought absolutely every version of Vegas from version 13 to now, and I'm amazed that something so simple and useful, that in Pinnacle still existed with 15- 20 years ago, we still don't have it in 2024!
