The ability to hide content using shortcodes on assets. For instance 'Hide' 'Show'.
Recently I'm having to add videos that only need to be deployed to specific players. All our players have tags relating to area, region and branch. In an ideal world I'd love to be able to upload the asset and set conditional playback using the tags of the player names. But instead I'm having to create a common tag that then needs to be added individually to each player that will display that asset. This takes a long time if you're dealing with over 100 players
