Display more information in Replays
Using Replay mode is already a great tool for determining where you went wrong in PVP situations so that you can do better next time, but it could be even more robust. Using the Show Nametags toggle allows us to see the health bars of the recorded dinos, but I think there should be more.
Additional toggles to show equipped abilities and their cooldowns as well as active buffs and debuffs with their time remaining would be great!
