It would be great if we could have a sort of DM Screen or Character Tracking tool set up similar to the initiative tracker that allowed us to set active PCs and NPCs and stats of the DMs choosing. The best use case for this would be Passive Perception. Beyond stats, it could also be useful if we could add buttons to the sheet to make group rolls for listed characters. An additional purpose could be a place to put journal pages and information the DM needs to reference often. See reference image:
