When running instances, I have a couple of suggestions that would really be nice to have:
1. Brightly highlight the name tag of the group member that is currently in focus. The past couple of days I think I have select a group member only to find that it didn't take
2. Allow Spacebar to be used to cycle through group members (eliminating clicks that don't take).
3. Put a small icon next to name tag when redeemed is still active.
4. Put a small numeric icon next to name tag when member has 1 or more negative effects.
