That's brilliant, why doesn't every program have this feature?! :D
Actually, the reason why is probably because it's hard to actually find the newest video... it seems to be opening the newest video file from my shared Dropbox folders, but not from where I actually do my video recording and editing (which is usually on another drive or a network folder depending on the project). If it could additionally search whatever folder the most recently loaded video was loaded from (which is probably always going to be my Banidcam / screen capture folder), or a `folders.txt` file I could edit with folder names to search, that'd be awesome =).
I tried putting a symlink from My Documents to the folder in question, but that didn't help either.
