It does function mostly in card combat, but the odometer visuals are buggy right now as of the recent update to the card combat plugin. There were a few notable visual errors before this recent update, like the gauges wouldn't go up or down during card selection (when an action restored or drained HP/MP/TP). Also, if you have multiple actors in battle, their odometers will appear in the card selection area and the odometer isn't showing for the party ui that shows in the top right corner. I hope Myth is able to update the compatibility for it again soon. Oh, and I wonder if he could add the ability to be attacked during your turn picking cards, it would make the odometer mechanic more hectic with it ticking down while you're making decisions.
