My congratulations on a fine product. One of the reasons I chose (and paid for !) it was that the support seems to be responsive.
I just have a minor suggestion. I finished a reasonably major project recently and on loading it again found unresolved references to several video files originally from Youtube that I had accidentally cleaned up. It was easy enough to find them again by entering the name of the mp4 into Youtube, but entering the name would be much faster/easier if we had this button:

Try this:

(Explanation in case you can't see the screenshot - I'm suggesting you add a "Copy name" button to the "resolve missing files" dialog which would copy the missing filename to the clipboard.)
