Would be good to be able to set a shared Client Review Playlist to auto-play through all Versions as a cut, like Screening Room does. Some studios will want their clients to review cuts this way, then go back and comment / annotate on each individual Version. Another option might be the ability to multi-select Versions in Client Review and 'Play Selected,' again like Screening Room.
