There is a very handy mod that has these features:
- Timers for active potion effects
- Arrow counter
- Visual Clock
- Armor Status
- Location ( X and Z )
- Compass ( Displaying the diriction your facing )
- Thirst Notifier
So as you can see, it's a very handy mod you should install.
And the ADMINS are okay with this mod.
PS: I'm not the maker of this mod!
