This might be a bit of a niche use case, but working as the Board Op in TV and film, I almost always need a video feed from one of the cameras, especially when circumstances necessitate the board being away from set/Video Village. With the new Apex consoles now having the new I/O garage and the ability to customize modules, I would absolutely love the ability to bring in a wired video feed, and have a "Video Tab" that I could put right along side my Direct Selects and Magic Sheets.
Again, this is probably a pretty specific case for tv/film people, although perhaps it may be used by those in theatre world as well?
