This mod shows the info about the mob you are looking at if you are in range of the mob. If you are, then information shows up on the top left corner. It shows health, mob type and the effects if the mob has any. This also works on multiplayer servers on players. This mod also shows the damage you deal on a mob or player, including if it is healed or not.
You bring up the creatures interface by looking at them or interacting with them.
The button for the configuration menu, by default is the "." key.
