PotionWarner

!Time

Warns you when your potion's about to run out

This mod is especially useful for pvp, so you don't forget to re-pot strength for example

To enable sounds, you should make a resourcepack containing:

assets
└── potionwarner
    └── sounds
        └── notify.ogg

_{yes i copied the output of tree}

the notify.ogg is the sound that will be played.
