I've been playing with Daggerheart and Blades in the Dark recently and both these games feature trackers (DM fear for Daggerheart and clocks for Blades) that are routinely used to track the passage of time or serve as a countdown timer or resource tracker. I'd love to have the ability to pin a small little sidebar area on the tabletop where these trackers can be displayed and always be in the same place no matter where the players' tokens are on the map.
