Am I missing something?
 

Does Vegas have the ability to show you on the explorer window what clips have/have not been used. For all it's bugs, Pinnacle Studio used to put a little green tick against all clips used in a project which made it very easy to see where you were/had left off.

I am working between various folders of footage, and finding myself having to constantly hunt through clips to see where I was.

A listing of all clips on the timeline with length of clip, start time end time of clip as well as other info.
